The v4l2_ctrl_query_fill_std() function wasn't one the best idea I ever had.
It doesn't add anything valuable that cannot be expressed equally well with
v4l2_ctrl_query_fill and only adds overhead.

Replace it with v4l2_ctrl_query_fill() everywhere it is used and remove it
from v4l2_common.c.

Hi there!

While having a look at the allocation of struct dvb_frontend in *_attach

redundant, and the attached patch removes these calls.
I also changed one case calling kmalloc and memset to kzalloc.

50144aeeb7 V4L/DVB (10652): uvcvideo: Add quirk to override wrong bandwidth value for Vimicro devices
At least 3 Vimicro cameras (0x332d, 0x3410 and 0x3420) fail to return correct
bandwidth information. The first model rounds the value provided by the host
to the nearest supported packet size, while the other two always request the
maximum bandwidth.

Introduce a device quirk to override the value returned by the device with an
estimated bandwidth computed by the driver from the frame size and frame rate,
and enable it for all Vimicro cameras.

4b10d3b626 V4L/DVB (10568): bttv: dynamically allocate device data
The bttv driver had static array of structures for up to 16 possible bttv
devices, even though few users have more than one or two.  The structures
were quite large and this resulted in a huge BSS segment.

Change the driver to allocate the bttv device data dynamically, which
changes "struct bttv bttvs[BTTV_MAX]" to "struct bttv *bttvs[BTTV_MAX]".
It would be nice to get ride of "bttvs" entirely but there are some
complications with gpio access from the audio & mpeg drivers.

To help bttvs removal along anyway, I changed the open() methods use the
video device's drvdata to get the driver data instead of looking it up in
the bttvs array.  This is also more efficient.  Some WARN_ON()s are added
in cases the device node exists by the bttv device doesn't, which I don't
think should be possible.

The gpio access functions need to check if bttvs[card] is NULL now.  Though
calling them on a non-existent card in the first place is wrong, but hard
to solve given the fundamental problems in how the gpio access code works.

This patch reduces the bss size by 66560 bytes on ia32.  Overall change is a
reduction of 66398 bytes, as the WARN_ON()s add some 198 bytes.

6f98700a5b V4L/DVB (10567): bttv: shrink muxsel data in card database
Over half of the card database was used to store muxsel data.  64 bytes
were used to store one 32 bit word for each of up to 16 inputs.

The Bt8x8 only has two bits to control its mux, so muxsel data for 16
inputs will fit into a single 32 bit word.  There were a couple cards that
had special muxsel data that didn't fit in two bits, but I cleaned them up
in earlier patches.

Unfortunately, C doesn't allow us to have an array of bit fields.  This
makes initializing the structure more of a pain.  But with some cpp magic,
we can do it by changing:
	.muxsel = { 2, 3, 0, 1 },
	.muxsel = { 2, 2, 2, 2, 3, 3, 3, 3, 1, 1 },
Into:
	.muxsel = MUXSEL(2, 3, 0, 1),
	.muxsel = MUXSEL(2, 2, 2, 2, 3, 3, 3, 3, 1, 1),

That's not so bad.  MUXSEL is a fancy macro that packs the arguments (of
which there can be one to sixteen!) into a single word two bits at a time.
It's a compile time constant (a variadic function wouldn't be) so we can
use it to initialize the structure.  It's important the the arguments to
the macro only be plain decimal integers.  Stuff like "0x01", "(2)", or
"MUX3" won't work properly.

I also created an accessor function, bttv_muxsel(btv, input), that gets the
mux bits for the selected input.  It makes it cleaner to change the way the
muxsel data is stored.

This patch doesn't change the code size and decreases the datasegment by
9440 bytes.

430390e67b V4L/DVB (10566): bttv: clean up mux code for IDS Eagle
This card apparently uses an external mux and the Bt878's mux should always
be set to MUX2.  The values for the external mux control bits were stored
in the muxsel field.  This meant that when changing inputs the driver would
switch the Bt878's mux to whatever value the external mux was supposed to
be set to, then eagle_muxsel() would switch it back to MUX2 and program the
external mux.  This creates an unnecessary switch of the Bt878's mux.

So change muxsel to be 2 for each input.  The external mux bits are just
"input&3" so they don't really need to be stored anywhere.  This also
eliminates the last non-standard use of the muxsel data.

13afaefc03 V4L/DVB (10565): bttv: fix external mux for RemoteVision MX
Old versions of the bttv driver would use the high nibble of an input's
muxsel value to program the GPIO lines enabled via gpiomask2.  Apparently
this was supposed to be for switching external audio muxes.  Anyway, the
code that did this was removed sometime in the pre-git 2.6 series.

The RemoteVision MX board used this feature to control an external video
mux and I guess no one noticed when they removed the code.

Move the extra gpio mux data out of the high nibble of muxsel and to
rv605_muxsel(), then have that function set the gpio lines with it.

From looking at the CD22M3494E datasheet, it seems like the mdelay(1) is a
much longer delay than necessary.  It looks like only around 20 ns is
necessary.

fb5deb1b9e V4L/DVB (10563): bttv: clean up mux code for IVC-120G
The card data for BTTV_BOARD_IVC120 set muxsel to a bunch of bogus values
(1 to 16), which the common mux code would use to set the Bt878's mux to
some random value.  Then the custom code in ivc120_muxsel() would change
the Bt878's mux to the right value (always MUX0).

Better to just make the muxsel data correct (all zeros, easy!) and get the
mux right to begin with.  Then the extra Bt878 mux setting code in
ivc120_muxsel() can be eliminated (the rest of the code for the IVC-120G's
external mux is still there of course).

This will help me clean up muxsel for some other changes.  It should also
get rid of an unnecessary mux switch when changing from certain inputs to
certain other inputs on the IVC-120G.

The code was using a muxsel value of -1U to indicate a digital input.  A
couple places in were checking of muxsel < 0 to detect this, which doesn't
work of course because muxsel is unsigned and can't be negative.

Only a couple cards had digital inputs and it was always the last one, so
for the card database create a one bit field that indicates the last input
is digital.  On init, this is used to set a new field in the bttv struct to
the digital input's number or UNSET for none.  This makes it easier to
check if the current input is digital.

4c548d4b28 V4L/DVB (10561): bttv: store card database more efficiently
The bttv card database is quite large and the data structure used to store
it wasn't very efficient.  Most of the field are only used at card
initialization time so it doesn't matter if they aren't efficient to
access.

Overall the changes reduce code size by 60 bytes in ia32.  The data size is
decreased by 5024 byes.  It is probably even more for 64-bit kernels.

Move the fields in the struct around to be sorted from largest to smallest.
This saves on padding space used for alignment.

Get rid of the unused digital_mode field.  Leave the setting as a comment
in the few cards entries that set it, in case someone ever writes the code.

Get rid of the unused audio_inputs field.  Leave the values in the card
entries in case someone ever writes code that might use it.

Get ride of the unused radio_addr field.  No card entries even set it to
anything interesting so it's not left as comments.  All the code that used
it was removed in commit v2.6.14-3466-g291d1d7 from Nov 8th 2005.

Reduce video_inputs to u8 as no card has more than 255 inputs (the most is
16).

Change tuner_addr to u8.  I2C addresses are only seven bits and 255 means
ADDR_UNSET, so everything fits.

Make has_radio a one bit flag.

Make the pll setting a two bit field.

Reduce svhs to four bits as no card has an s-video input above 9.  Change
the value for no s-video input from UNSET (which is -1U and out of range of
four bits) to NO_SVHS (which is now 15).

abb0362f49 V4L/DVB (10560): bttv: make tuner card info more consistent
The bttv card database structure had a "tuner" field that was the input
number of the tuner input or UNSET for no tuner.  However, the only values
it could ever be are 0 and UNSET.  Having a tuner on an input other than 0
didn't work and was never used.

There is also a "tuner_type" field that can be set to TUNER_ABSENT to
indicate no tuner, which makes "tuner = UNSET" redundant.  In many cases,
tuner_type was set to UNSET when there was no tuner, which isn't quite
correct.  tuner_type == UNSET is supposed to mean the tuner type isn't yet
known.

So, I changed cards where "tuner == UNSET" to always have tuner_type of
TUNER_ABSENT.  At this point the tuner field is redundant, so I deleted it.

I have the card setup code set the card's tuner_type (not the card type's
tuner_type!) to TUNER_ABSENT if it hasn't yet been set at the end of the
setup code.  Various places that check if the card has a tuner will now
look for this instead of checking the card type's "tuner" field.

Also autoload the tuner module before issuing the TUNER_SET_TYPE_ADDR I2C
client call instead of after issuing it.

Overall, on ia32 this decreases compiled code size by about 24 bytes and
reduces the data size by 640 bytes.

72134a6d51 V4L/DVB (10559): bttv: Fix TDA9880 norm setting code
The code to set the norm for the TDA9880 analog demod was comparing
btv->norm, an index into the bttv driver's norm array, to V4L2_STD_NTSC,
which is a bit flag that's part of the V4L2 API.  This doesn't work of
course and results in the PAL path always being taken.

What's more, it modified the bttv_tvcards[] entries for cards using the
TDA9880.  This is wrong because changing the norm on one card will also
affect other cards of the same type.  Writing to bttv_tvcards is also bad
because it should be read-only or even devinitdata.

Changing the norm would also cause the audio to become unmuted.

Have the code get called for both norm setting and audio input setting
(which where the gpios are set) to avoid needed to modify bttv_tvcards.

Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any
data because there was some logic put in with an adev->shutdown variable which did not seem warranted in my humble opinion.
It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and
reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow.

517efa89ac V4L/DVB (10512): tda1004x: Fix eeprom firmware load on boards with 16MHz Xtal
For i2c normal work, we need to slow down the bus speed. However, the
slow down breaks the eeprom firmware load. So, use normal speed for
eeprom booting and then restore the i2c speed after that.

It should also be noticed that no other I2C transfer should be in course
while booting from eeprom, otherwise, tda10046 goes into an instable
state. So, proper locking are needed at the i2c bus master.

Tested with saa7134 MSI TV @nyware A/D board, that comes with an eeprom
with firmware version 29.

The gate control logic is broken: several routines just keep it open;
other rotines close it properly; there are even other routines that
assumes that it is open without really checking or opening it.

Instead of having to manually handle the gate control and having such
troubles, let a sub-routine take care of the gate, opening it before
i2c_transfer and closing it after that. This avoids leaving the gate
into a random state.

812b1f9d54 V4L/DVB (10446): cx18: Finally get sliced VBI working - for 525 line 60 Hz systems at least
Sliced VBI, in the manner that ivtv implements it as a separate data stream,
now works for 525 line 60 Hz systems like NTSC-M.  It may work for 625 line
50 Hz systems, but I have more engineering work to do, to verify it is operating
properly.  Sliced data insertion into the MPEG PS should be working, but is
untested.

466df46484 V4L/DVB (10445): cx18: Process Raw VBI on a whole frame basis; fix VBI buffer size
The cx23418 appears to send Raw VBI buffers with a PTS on a per frame
basis, not per field, so process Raw VBI on a whole frame basis and reduce
some complexity.  Fix VBI buffer size computation to handle a whole
frame of Raw VBI for a 625 line system, which is the worst case and will
work for 525 lines systems as well.

01cbc214cf V4L/DVB (10444): cx18: Fix sliced VBI PTS and fix artifacts in last raw line of field
Fixed an endianess problem with the collection of the PTS from
the VBI buffer given to us by the encoder.  Also extrapolated the
last 12 bytes of the last line of each field, to remove artifacts
created by removing the first 12 bytes of each field for raw VBI.

dcc0ef8820 V4L/DVB (10442): cx18: Fixes for enforcing when Encoder Raw VBI params can be set
The Encoder will only allow the Raw VBI parameters, along with a number of
other API parameters, to take effect when no analog captures are in
progress.  These parameters must be set before the first analog capture starts,
be it MPEG, VBI, YUV, etc., and cannot be changed until the last one stops.  It
is not obvious to me what capture channel API parameters are shared and which
ones must be set per capture channel, so set them all for every analog
capture channel start up.  This fixes the driver so that VBI capture can be
started up after the MPEG capture is going.

776fa86988 V4L/DVB (10440): cx18: Fix presentation timestamp (PTS) for VBI buffers
The old code from ivtv used a CX23415/6 PTS, which was simply left at 0 in the
cx18 driver.  Since the CX23418 gives us what I think is a PTS (or some other
90 kHz clock count) with each VBI buffer, this change has the cx18 driver use
that as a PTS.

strncpy is unsafe as it doesn't append a terminating NUL character when the
source string doesn't fit in the destination buffer. Replace it with strlcpy.
strncat is misused as its size argument refers to the source string, not the

94b5ff9cf3 V4L/DVB (10259): pvrusb2: Code module name directly in printk
The name of the pvrusb2 module is not likely to ever change, and there
are plenty of other places where the name is directly coded, so there
is little utility in using a macro to infer the module name here.  In
addition, using that macro complicates other uses of the driver
involving older kernels where this macro works differently.  Yes I
know for many places we don't have to worry about that.  But my
alternative is that I have to build special logic in the pvrusb2
standalone driver to special-case what is otherwise costmetic and that
is just plain nuts for something as trivial as this, especially since
this change does not at all have any compile time or run time impact
on the driver.  I'm just removing a nicety that didn't have a lot of
value here to begin with.

be4f4aecf8 V4L/DVB (10239): pvrusb2: Fix misleading comment caused by earlier commit
Previous v4l-dvb changeset id 4cc8ed11e2e0 changed the pvrusb2-hdw
internal API regarding i2c chip debug register access.  However that
change failed to also update the corresponding function comment
describing the API.  As driver maintained I never saw a request for an
ack on that change; there probably should have been one especially
since the manner in which this API operates was changed - its
interface is now entangled with a v4l specific struct and I would have
preferred to keep this API clear of moving-target v4l-isms such as
this one if at all possible which is why I had done it the way I did
before.  But whatever.  This commit at least fixes the comment issue.

e164b58a84 V4L/DVB (10211): vivi: Implements 4 inputs on vivi
This patch adds the capability of selecting between 4 different inputs
on vivi driver. Input 0 is the normal color bar, while inputs 1-3 are
modified color bars.

This allows testing input selection on userspace applications and
serves as an implementation model for other drivers.

The current approach allows a maximum of 10 different inputs, since the
input name generator assumes that we need just one digit to present the
input. It shouldn't be hard to modify it to present a bigger name of
inputs, but, in fact, it doesn't make much sense of doing it for this
test driver.

7ebc8d56f4 [ARM] pxa: move DMA registers definitions into <mach/dma.h>
1. Driver code where pxa_request_dma() is called will most likely
   reference DMA registers as well,  and it is really unnecessary
   to include pxa-regs.h just for this. Move the definitions into
   <mach/dma.h> and make relevant drivers include it instead of
   <mach/pxa-regs.h>.

2. Introduce DMAC_REGS_VIRT as the virtual address base for these
   DMA registers. This allows later processors to re-use the same
   IP while registers may start at different I/O address.

382c5546d6 V4L/DVB (10694): [PATCH] software IRQ watchdog for Flexcop B2C2 DVB PCI cards
With (some) Technisat cards you cannot run multiple DVB applications
in parallel and switch the channel at the same time.

There seems to be a problem on the interfaces or even inside the flexcop-device
that can't handle interruption on the streaming interface.

This patch adds a watchdog to check whether data is supposed to come in
(streaming PIDs are requested) and if no data is seen within 400ms (default) it
resets the streaming/pid-filtering hardware.

This patch is urgently needed to support the rev 2.8 of the hardware and solves
problem occassionally seen on older hardware.

As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should
set the struct device for the card before registering the card instance.
This will add the correct /sys/class/sound/cardN/device symlink, so HAL
can see the device and ConsoleKit sets its ACL permissions for the
logged-in user.

For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2),

firedtv: reinstate debug logging option

    Henrik Kurelid tells me that FCP debug logging (which I removed during
    cleanups) is still useful when working on driver issues together with
    end users.  So bring it back in an updated form with only 60% of the
    original code footprint.

    Logging can be enabled with
    # echo -1 > /sys/module/firedtv/parameters/debug

    1 instead of -1 enables only FCP header logging,
    2 instead of -1 enables only hexdumps of the entire FCP frames.
    0 switches logging off again.

    This loop is unnecessary because

firedtv: register input device as child of a FireWire device

    Instead of one virtual input device which exists for the whole lifetime
    of the driver and receives events from all connected FireDTVs, register
    one input device for each firedtv device.  These input devices will show
    up as children of the respective firedtv devices in the sysfs hierarchy.

    However, the implementation falls short because of a bug in userspace:
    Udev's path_id script gets stuck with 100% CPU utilization, maybe
    because of an assumption about the maximum ieee1394 device hierarchy
    depth.

    To avoid this bug, we use the fw-host device instead of the proper
    unit_directory device as parent of the input device.

    There is hope that the port to the new firewire stack won't be inhibited
    by this userspace bug because there are no fw-host devices there.

    Now that nodemgr was enhanced to match against the root directory's

    prevent firedtv to be bound to wrong devices by accident.

    Also add the AV/C software version ID to the match flags for

Combination of the following changes:

firedtv: fix remote control input

    and update the scancode-to-keycode mapping to a current model.  Per
    default, various media key keycodes are emitted which closely match what
    is printed on the remote.  Userland can modify the mapping by means of
    evdev ioctls.  (Not tested.)

    The old scancode-to-keycode mapping is left in the driver but cannot be
    modified by ioctls.  This preserves status quo for old remotes.

firedtv: replace semaphore by mutex

    firesat->avc_sem and ->demux_sem have been used exactly like a mutex.
    The only exception is the schedule_remotecontrol tasklet which did a
    down_trylock in atomic context.  This is not possible with
    mutex_trylock; however the whole remote control related code is
    non-functional anyway at the moment.  This should be fixed eventually,
    probably by turning the tasklet into a worqueue job.

    Convert everything else from semaphore to mutex.

    Also rewrite a few of the affected functions to unlock the mutex at a
    single exit point, instead of in several branches.

df4846c352 firesat: update isochronous interface, add CI support
I have finally managed to get the CI support for the card working. The
implementation is a bare minimum to get encrypted channels to work in
kaffeine. It works fine with my T/CI card. Now and then I get an AVC
timeout and have to retune a channel in order to get it to work. Once
the CAM seemed to hang so I needed to remove and insert it again. I.e.
there are a number of glitches.

The latest version contains the following changes:

  - Implemented the new hpsb iso interface so that data can be received
    from the card
  - Reduced some timers for demux setup which caused scanning to timeout
  - Added possibility to unload driver
  - Added support for getting C/N ratio
  - Added two debug parameters to the driver; ca_debug and
    avc_comm_debug.
  - Added CI support that works for me in kaffeine
  - Started working on CI MMI support. It now supports:
      o Enter menu
      o Receiving MMI objects
  - Added support for 64-bit platforms
  - Corrected DVB-C modulations problems

up before the video_ioctl2 call, causing random crashes.

This change set is wrong. The affected functions cannot be called from

I agree, this is bad.  The demuxer is far too much work to be done with

ef88f2b563 V4L/DVB (10527): tuner: fix TUV1236D analog/digital setup
As reported by David Engel <david@istwok.net>, ATSC115 doesn't work
fine with mythtv. This software opens both analog and dvb interfaces of
saa7134.

What happens is that some tuner commands are going to the wrong place,
as shown at the logs:

Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: using tuner params #0 (ntsc)
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808
Feb 12 20:37:48 opus kernel: tuner 1-0061: tv freq set to 67.25
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc)
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01

This happens due to a hack at TUV1236D analog setup, where it replaces
tuner address, at 0x61 for 0x0a, in order to save a few memory bytes.

The code assumes that nobody else would try to access the tuner during
that setup, but the point is that there's no lock to protect such
access. So, this opens the possibility of race conditions to happen.

Instead of hacking tuner address, this patch uses a temporary var with
the proper tuner value to be used during the setup. This should save
the issue, although we should consider to write some analog/digital
lock at saa7134 driver.

 =======================

The culprit in the trace is snd_pcm_action() which invokes a spin lock
which disables pre-emption which disables an IRQ which causes the
__might_sleep() function to fail the irqs_disabled() test.  Since
pre-emption is enabled then it is safe to de-allocate the memory if
you first unlink each URB.  In this instance you are safe since
pre-emption is disabled.  If pre-emption and irqs are not disabled then
call usb_kill_urb(), else call usb_unlink_urb().

6dbe7af37d V4L/DVB (10265): budget.c driver: Kernel oops: "BUG: unable to handle kernel paging request at ffffffff
I'm using a "Hauppauge WinTV-NOVA-T DVB card" of PCI id "13c2:1005" with
kernel 2.6.27.9.

I've recently experienced the following fairly consistent kernel oops on
startup in grundig_29504_401_tuner_set_params from budget.c. As you
might expect, following this failure, the card doesn't work.

I'm not a kernel developer, nevertheless I seem to have managed to track
this down to a non-existent initialisation of
budget->dvb_frontend->tuner_priv.

The attached patch fixes the problem for me (and I've managed to tune
the card successfully as a result), but I don't know of anyone else
using the driver so I can't test it on other people.

Please let me know if this works for you or if I've done something
terribly wrong ;-(

ba390f0055 V4L/DVB (10250): cx25840: fix regression: fw not loaded on first use
With the conversion to v4l2_subdev one bit of code was accidentally dropped:
on receiving the first command the driver has to load the fw. A new init()
command was introduced to do that explicitly for bridge drivers that are
converted to use v4l2_subdev, but old drivers that are not yet converted
no longer worked.

This patch fixes this regression for these old drivers.

db4b2d193c V4L/DVB (10233): [PATCH] Terratec Cinergy DT XS Diversity new USB ID (0ccd:0081)
The following patch adds support for a new version of the
Terratec Cinergy DT USB XS Diversity Dual DVB-T TV tuner stick.
The USB ID of the new stick is 0ccd:0081.
The hardware of the stick has changed, when compared to the first version of
this stick, but it still uses quite standard components, so that only minor
changes are needed to the sources.

The patch has been successfully tested with hotplugging the device and then
2 x tzap and 2 x mplayer, to watch two different TV programs simultaneously.

The stick works with both, the old and new firmwares:
- dvb-usb-dib0700-1.10.fw and
- dvb-usb-dib0700-1.20.fw

The zoran driver does a module_get/put of THIS_MODULE on device open/close.
This isn't necessary as the kernel does this automatically.

The driver should only use the kernel mapped io address, zr36057_mem, and
not the PCI bus address, zr36057_adr.  Since the latter is only printed out
once, there is no need to save it in the driver data structure.

There was some old code that looked like it was for the Alpha architecture
which would use the PCI bus address.  It probably no longer applies to
modern kernels.

601139e083 V4L/DVB (10223): zoran: Remove global device array
The driver was keeping a global array with an entry for each zoran device
probed.  It was a leftover from when the driver didn't dynamically allocate
the driver data for each device.

There was only one use left, in the video device's ->open() method, looking
up the struct zoran for the opened device from the minor number.  This can
be done better with video_get_drvdata().

Since zoran_num is now only used in the pci driver's ->probe() method, it
doesn't need to be an atomic_t and be static.  There is a race if multiple
zoran cards could be probed at the same time, but currently the probe
method for a given driver is single threaded.

Analog support for HVR-1250 has not been completed, but does exist for
the HVR-1800.

Since both cards use the same driver, it tries to create the analog
dev for both devices, which is not possible.

This causes a NULL error to show up in video_open and mpeg_open.

-Mark

Iterations through the cx23885_devlist must check for NULL
pointers as some supported devices only have DVB support at the moment.
Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800
installed.
