82e7dbbd4a [media] em28xx: initial support for HAUPPAUGE HVR-930C again
With this patch I try again to add initial support for HVR930C.

Tested only DVB-T, since in Italy Analog service is stopped.

Actually "scan -a0 -f1", find only about 50 channel while 400 should
be available.

ecb3b2b35d USB: convert drivers/media/* to use module_usb_driver()
This converts the drivers in drivers/media/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

2440f7aff4 [media] Properly implement ITU-T J.88 Annex C support
The Annex C support were broken with the previous implementation,
as, at xc5000 and tda18271c2dd, it were choosing the wrong bandwidth
for some symbol rates.

At DRX-J, it were always selecting Annex A, even having Annex C
support coded there.

39ce61a846 [media] dvb: Allow select between DVB-C Annex A and Annex C
DVB-C, as defined by ITU-T J.83 has 3 annexes. The differences between
Annex A and Annex C is that Annex C uses a subset of the modulation
types, and uses a different rolloff factor. A different rolloff means
that the bandwidth required is slicely different, and may affect the
saw filter configuration at the tuners. Also, some demods have different
configurations, depending on using Annex A or Annex C.

So, allow userspace to specify it, by changing the rolloff factor.

ff17999184 [media] ttusb2: Don't use stack variables for DMA
The ttusb2_msg function uses on-stack variables to submit commands to
dvb_usb_generic.  This eventually gets to the DMA api layer and will throw a
traceback if the debugging options are set.

This allocates the temporary buffer variables with kzalloc instead.

4860c73804 staging: Move media drivers to staging/media
In practice, it is being hard to distinguish when a patch
should go to staging tree or to the media tree. Better
to distinguish it, by putting the media drivers at a
separate staging directory. Newer staging drivers that include
anything with "dvb*.h", "v4l2*.h" or "videodev2.h" should
go to the drivers/staging/media tree.

e305288547 [media] it913x-fe changes to power up and down of tuner
Currently the tuner is constantly powered causing these effects.
1. Remembering last tune channel causing corruptions of changing channel.
2. Causing corruption on other frontend.
3. Higher current in standby of demodulator with clock running.

Power Up
Tuner on -> Frontend suspend off -> Tuner clk on
Power Down
Frontend suspend on -> Tuner clk off -> Tuner off

With VDR streaming HDTV into network, generating an interrupt once per 16kb,

Fix leaking almost 64kb data from the previous TS after changing the TS.
One effect of the old version was, that the DMA transfer and driver's

The following patch provides wider carrier search.

As with existing code search starts at MSB aligned. The boundary
is widened to start at -9.  In order to save time, if no carrier is
detected at the start it advances to the next alignment until carrier
is found.

The stv0288 will detect a DVB-S2 carrier on all steps , a
time out of 11 steps is introduced to drop out of the loop.

In stv0288_set_symbol carrier and timing loops are restored to
default values (inittab) before setting the symbol rate on each tune. A
slight drift was noticed with full scan in the higher IF frequencies of
each band.

fc61ccd35f [media] vp7045: fix buffer setup
dvb_usb_device_init calls the frontend_attach method of this driver which
uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to
be allocated before that happens.

Luckily we can use the whole private data as the buffer as it gets separately
allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for
use via usb_control_msg.

This fixes a
	BUG: unable to handle kernel paging request at 0000000000001e78

4b5d01e9f6 [media] dvb-usb: fix streaming failure on channel change
This fixes a bug introduced by a previous changeset entitled,
[media] dvb-usb: refactor MFE code for individual streaming config per frontend

As reported by Antti Palosaari, This error is shown by VLC when channel changed:

[0x7f1bbc000cd0] dvb access error: DMXSetFilter: failed with -1 (Invalid argument)
[0x7f1bbc000cd0] dvb access error: DMXSetFilter failed
[0x7f1bbc32f910] main stream error: cannot pre fill buffer

After my own investigations, I've determined that this error case occurs when
the application stops streaming but leaves the frontend and dvr devices open.
A typical example of this usage would be a channel change operation while
watching live television. The error occurs when the application attempts to
stream after tuning to the new channel.

To prevent this error, don't set adap->active_fe to -1 unless the application
closes the device.

0b8bd83cf3 [media] em28xx: don't sleep on disconnect
The DVB framework will try to power-down an adapter that no-one is using
any more, but this assumes that the adapter is still connected to the
machine. That's not always true for a USB adapter, so disable the sleep
operations when the adapter has been physically unplugged.

This prevents I2C write failures with error -19 from appearing
occasionally in the dmesg log.

3f5c14d3d3 [media] drivers/media: do not use EXTRA_CFLAGS
Usage of these flags has been deprecated for nearly 4 years by:

    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

e9013fb6eb [media] ddbridge: fix ddb_ioctl()
There were a several problems in this function:

1) Potential integer overflow in the comparison:
	if (fio.write_len + fio.read_len > 1028) {

2) If the user gave bogus values for write_len and read_len then
   returning -EINVAL is more appropriate than returning -ENOMEM.

3) wbuf was set to the address of an array and could never be NULL
   so I removed the pointless NULL check.

4) The call to vfree(wbuf) was improper.  That array is part of a
   larger struct and isn't allocated by itself.

5) flashio() can't actually fail, but we may as well add error
   handling in case this changes later.

6) In the default case where an ioctl is not implemented then
   returning -ENOTTY is more appropriate than returning -EFAULT.

This patch implements an i2c_gate_ctrl op for the cxd2820r. Thanks to Robert
Schlabbach for identifying the register address and field to set.

The old i2c intercept code that prefixed messages with a passthrough byte has
been removed and the PCTV nanoStick T2 290e entry in em28xx-dvb has been
updated appropriately.

Tested for DVB-T2 use; I would appreciate it if somebody with DVB-C capabilities
could test it as well - from inspection I cannot see any problems.

8513e14457 [media] dvb-core, tda18271c2dd: define get_if_frequency() callback
Tuners in general convert a high frequency carrier into an Intermediate
Frequency (IF).

Digital tuners like tda18271, xc3028, etc. generally allow changing the IF
frequency, although they generally have recommented settings for the IF.
Analog tuners, have a fixed IF frequency, that depends on the physical
characteristics of some analog components.

For digital tuners, it makes sense to have ways to configure IF,
via the tuner's configuration structure, like what's done inside the
tda18271-fe maps.

The demods need to know what IF is used by the tuner, as it will need
to convert internally from IF into baseband. Currently, the bridge driver
needs to fill a per-demod configuration struct for it, or pass it via
a dvb_attach parameter.

The tda18271 datasheet recommends to use different IF's for different
delivery system types and for different bandwidths.

The DRX-K demod also needs to know the IF frequency in order to work,
just like all other demods. However, as it accepts different delivery
systems (DVB-C and DVB-T), the IF may change if the standard and/or
bandwidth is changed.

So, the usual procedure of passing it via a config struct doesn't work.

One might try to code it as two separate IF frequencies, or even as a
table in function of the delivery system and the bandwidth, but this
will be messy.

So, it is better and simpler to just add a new callback for it and
require the tuners that can be used with MFE frontends like drx-k
to implement a new callback to return the used IF.

cf845297d5 [media] tda18271c2dd: Fix saw filter configuration for DVB-C @6MHz
Currently, the driver assumes that all QAM carriers are spaced with
8MHz. This is wrong, and may decrease QoS on Countries like Brazil,
that have DVB-C carriers with 6MHz-spaced.

Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to
associate the symbol rate with the bandwidth needed for it.

For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is:
	6 MHz / 1.15 = 5217391 Bauds
For  ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is:
	6 MHz / 1.13 = 5309735 Bauds.

As this tuner is currently used only for DRX-K, and it is currently
hard-coded to annex A, I've opted to use the roll-off factor of 0.15,
instead of 0.13.

If we ever support annex C, the better would be to add a DVB S2API
call to allow changing between Annex A and C, and add the 0.13 roll-off
factor to it.

This code is currently being used on other frontends, so I think we
should later add a core function with this code, to warrant that
it will be properly implemented everywhere.

320ed23ebf [media] drxk: Fix a bug at some switches that broke DVB-T
The error propagation changeset c23bf4402 broke the DVB-T
code.

The legacy way for propagate errors was:

do {
	status = foo_func()
	if (status < 0)
		break;
} while (0);
return status;

However, on a few places, it was doing:
do {
	switch(foo) {
	case bar:
		status = foo_func()
		if (status < 0)
			break;
		break;
	}
	switch(foo2) {
	case bar:
		status = foo_func()
		if (status < 0)
			break;
		break;
	}
	...
} while (0);
return (status)

The inner error break were not working, as it were breaking only
the switch, instead of the do. The solution used were to do a
s/break/goto error/ at the inner breaks, but preserving the last
break. Onfortunately, on a few switches, the replacement were
applied also to the final break for the case statements.

Fix the broken logic, by reverting them to break, where pertinent,
in order to fix DVB-T support.

while we don't do that, we need to patch em28xx-dvb in order
to do cope with ngene/ddbridge magic.

While here, document why drxk_t_release should do nothing.

This reverts commit a3e4adf274f86b2363fedaa964297cb38526cef0.

As pointed by Andread Oberritter <obi@linuxtv.org>:

	That's wrong, because the array size is DTV_MAX_COMMAND + 1.
	Using the ARRAY_SIZE macro instead might reduce the confusion.

Also, changeset 3995223038 already fixed this issue.

8afe9119e2 [media] media, Micronas dvb-t: Fix mem leaks, don't needlessly zero mem, fix spelling
In drivers/media/dvb/frontends/drxd_hard.c::load_firmware() I see 3
small issues:

 1) When the 'fw' variable goes out of scope we'll leak the memory
 allocated to it by request_firmware() by neglecting to call
 release_firmware().

 2) After a successful request_firmware() we allocate fw->size bytes
 of memory using kzalloc() only to immediately overwrite all that
 memory with memcpy(), so asking for zeroed memory seems like wasted
 effort - just use kmalloc().

 3) In one of the error messages "no memory" lacks a space and is
 written as "nomemory".

This patch fixes all 3 issues.

5eee2bb270 [media] drxk: Add a fallback method for QAM parameter setting
The QAM standard is set using this scu_command:
	SCU_RAM_COMMAND_STANDARD_QAM |
	SCU_RAM_COMMAND_CMD_DEMOD_SET_PARAM

The driver implements a version that has 4 parameters, however,
Terratec H5 needs to break this into two separate commands, otherwise,
DVB-C doesn't work.

With this fix, scan is now properly working and getting the
channel list:
>>> tune to: 609000000:INVERSION_AUTO:5217000:FEC_3_4:QAM_256
>>> tuning status == 0x00

Better than ERROR -3. This happens with Terratec H5 firmware.

It adds 2 new error conditions, and something useful to track
what the heck is that.

I suspect that the scu_command is dependent on the firmware
revision.

90796acad0 [media] drxk: Improves the UIO handling
The driver is too limited: it assumes that UIO is used only for
controlling the antenna, and that only UIO-1 is in usage. However,
from Terratec H7 driver [1], 3 UIO's can be used. In fact, it seems
that H7 needs to use all 3. So, make the code generic enough to handle
the most complex scenario. For now, only antena GPIO can be specified,
but is is easier now to add the other GPIO/UIO needs.

be44eb283b [media] drxk: Proper handle/propagate the error codes
This driver is very big and complex. An error happening in the middle
of any initialization may cause the frontend to not work. So, it
needs to properly propagate error codes internally and to userspace.

Also, printing the error codes at the places it happened helps to
discover were's a bug at the code.

Before this change, a do { } while (0) loop and lots of breaks inside
were used to propagate errors. While this works, if there are
loops inside other loops, it could be easy to forget to add another
break, causing the error to not abort the function.

Also, as not all functions were reporting errors, it is hard to
discover why something failed.

5e66b87840 [media] drxk: remove _0 from read/write routines
The normal 16-bits read routine is called as "Read16_0". This is
due to a flags that could optionally be passed. Yet, on no places
at the code, a flag is passed there.

The same happens with 16-bits write and 32-read/write routines,
and with WriteBlock.

Also, using flags, is an exception: there's no place currently using
flags, except for an #ifdef at WriteBlock.

Rename the function as just "read16", and the one that requires flags,
as "read16_flags".

This helps to see where the flags are used, and also avoid using
CamelCase on Kernel.

This concerns only the CI (CAM) related code of firedtv of which I know
little.  Let's just pass through the error returns of lower level I/O
code where applicable, and -EACCES (permission denied) when a seemingly
valid but negative FCP response or an unknown-to-firedtv CA message is
received.

2d1969312d [media] dvb_frontend: fix race condition in stopping/starting frontend
Attached is a patch which addresses a race condition in the DVB core
related to closing/reopening the DVB frontend device in quick
succession.  This is the reason that devices such as the HVR-1300,
HVR-3000, and HVR-4000 have been failing to scan properly under MythTV
and w_scan.

The gory details of the race are described in the patch.

Devin

There is a race condition exhibited when channel scanners such as w_scan and
MythTV quickly close and then reopen the frontend device node.

Under normal conditions, the behavior is as follows:

1.  Application closes the device node
2.  DVB frontend ioctl calls dvb_frontend_release which sets
    fepriv->release_jiffies
3.  DVB frontend thread *eventually* calls dvb_frontend_is_exiting() which
    compares fepriv->release_jiffies, and shuts down the thread if timeout has
    expired
4.  Thread goes away
5.  Application opens frontend device
6.  DVB frontend ioctl() calls ts_bus_ctrl(1)
7.  DVB frontend ioctl() creates new frontend thread, which calls
    dvb_frontend_init(), which has demod driver init() routine setup initial
    register state for demod chip.
8.  Tuning request is issued.

The race occurs when the application in step 5 performs the new open() call
before the frontend thread is shutdown.  In this case the ts_bus_ctrl() call
is made, which strobes the RESET pin on the demodulator, but the
dvb_frontend_init() function never gets called because the frontend thread
hasn't gone away yet.  As a result, the initial register config for the demod
is *never* setup, causing subsequent tuning requests to fail.

If there is time between the close and open (enough for the dvb frontend
thread to be torn down), then in that case the new frontend thread is created
and thus the dvb_frontend_init() function does get called.

The fix is to set the flag which forces reinitialization if we did in fact
call ts_bus_ctrl().

This problem has been seen on the HVR-1300, HVR-3000, and HVR-4000, and is
likely occuring on other designs as well where ts_bus_ctrl() actually strobes
the reset pin on the demodulator.

Note that this patch should supercede any patches submitted for the
1300/3000/4000 which remove the code that removes GPIO code in
cx8802_dvb_advise_acquire(), which have been circulating by users for some
time now...

b7f080cfe2 net: remove mm.h inclusion from netdevice.h
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

Here is patch for GPIO's handling.
It allows to support I2C on GPIO's and per board LNB control through GPIO's.
Also incuded some support for Hendrik Skarpeid card.
For those, who needs to tweak the driver,
I think it is clear how to change and test GPIO's for LNB and other GPIO related stuff now.

Remove old DVB-T2 freq module param and detect DVB-T/T2 automatically.

Implementation is trial and error, if DVB-T does not lock try DVB-T2
and vice versa. That's done by replacing normal DVBFE_ALGO_SW with
DVBFE_ALGO_CUSTOM which gives better control for tuning process.

DVB-C still uses normal software ZigZag, DVBFE_ALGO_SW.

08921ac9e9 [media] Media, DVB, Siano, smsusb: Avoid static analysis report about 'use after free'
In drivers/media/dvb/siano/smsusb.c we have this code:
 ...
               kfree(dev);

               sms_info("device %p destroyed", dev);
 ...

at least one static analysis tool (Coverity Prevent) complains about this
as a use-after-free bug.
While it's true that we do use the pointer variable after freeing it, the
only use is to print the value of the pointer, so there's not actually any
problem here. But still, silencing the complaint is trivial by just moving
the kfree() call below the sms_info(), so why not just do it?. It doesn't
change the workings of the code in any way, but it makes the tool shut up.
The patch below also removes a rather pointless blank line.
