24be689bfb [media] pwc: Use one shared usb command buffer
The pwc driver used to:
1. kmalloc a buffer
2. memcpy data to send over usb there
3. do the usb_control_msg call (which does not work with data on the stack)
4. free the buffer

For every usb command send. This patch changes the code to instead malloc
a buffer for this purpose once and use it everywhere.

938d5b9e7c [media] pwc: Avoid sending mode info to the camera when it is not needed
Since we always do a set_video_mode on stream start, there is no need

d167a85c5f [media] pwc: Fix pixfmt handling
Before this patch various code in the mode setting patch checked
pdev->pixfmt, but that was not set until the mode setting succeeded, so
it was looking at the old pixfmt! This patch fixes this by making the
pixfmt a parameter to set_video_mode, and setting it from set_video_mode
on success.

f4b1952a45 [media] dvb-core: fix a regression with MythTV
As reported by Lawrence[1], MythTV 0.24.1 does the wrong thing
with a DVBv5 call: it fills the delivery system with
SYS_UNDEFINED, expecting that the DVB core would work with that.

This used to work by accident, as the DVB core were missing the
check for the supported delivery systems. Yet, fixing it
is easy, so let's add a logic to handle this case, to
provide backward compatibility.

90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

ebe967492c mb86a20s: Add a few more register settings at the init seq
Some time ago, Manoel sent us a patch adding more stuff
to the init sequence. However, his patch were also doing
non-related stuff, by changing the init logic without
any good reason. So, it was asked for him to submit a
patch with just the data that has changed, in order to
allow us to better analyze it.

As he didn't what it was requested, I finally found some
time to dig into his init sequence and add it here.

Basically, new stuff is added there. There are a few changes:

1) The removal of the extra (duplicated) logic that puts
   the chip into the serial mode;
2) Some Viterbi VBER measurement init data was changed from
   0x00 to 0xff for layer A, to match what was done for
   layers B and C.

None of those caused any regressions and both make sense
on my eyes.

The other parameters additions actually increased the
tuning quality for some channels. Yet, some channels that
were previously discovered with scan disappered, while
others appeared instead. This were tested in Brasilia,
with an external antena.

At the overall, it is now a little better. So, better to
add these, and then try to figure out a configuration that
would get even better scanning results.

1020d13d50 [media] em28xx: increase maxwidth for em2800
The MaxPacketSize for em2800 based devices is too small to capture at full resolution.
Therefore scale down when the maximum frame size is selected.
The previous workaround that simply reduced the X resolution cannot be used
because it crops a part of the input as
the em2800 can only scale down with a factor of 0.5.

reverts commits 1ca31892e and fb3de0398a.

ca80cf6048 [media] em28xx: Do not modify EM28XX_R06_I2C_CLK for em2800
writing the EM28XX_R06_I2C_CLK register leads to the problem that the
i2c bus on the Terratec Cinergy 200 USB is no longer usable when the
system is rebooted.

The device needs to be unplugged in order to bring it back to life.

em28xx_pre_card_setup() like it is already done in em28xx_card_setup().

d07b901f9d [media] af9005, af9015: use symbolic names for USB id table indices
The af9005_properties and af9015_properties tables make use of USB ids
from the USB id tables with hardcoded indices, as in
"&af9015_usb_table[30]".  Adding new entries before the end breaks
such references, so everyone has had to carefully tiptoe to only add
entries at the end of the list.

In the spirit of "dw2102: use symbolic names for dw2102_table
indices", use C99-style initializers with symbolic names for each
index to avoid this.  In the new regime, properties tables referring
to the USB ids have names like "&af9015_usb_table[CINERGY_T_STICK_RC]"
that do not change meaning when items in the USB id table are
reordered.

7a6f6c29d2 [media] cx231xx: use URB_NO_TRANSFER_DMA_MAP on URBs allocated with usb_alloc_urb()
URBs allocated with usb_alloc_urb() are allocated from DMA-coherent
areas, and therefore it is not necessary to call dma_map_single() on
such buffers. Worst, on ARM, calling dma_map_single() on a
DMA-coherent buffer will trigger a BUG_ON() in
arch/arm/mm/dma-mapping.c.

Therefore, we mark all URBs allocated with usb_alloc_urb() with the
URB_NO_TRANSFER_DMA_MAP transfer_flags, so that the USB core does not
do dma_map_single()/dma_unmap_single() on those buffers.

This is similar to 882787ff8f for the
gspca driver, and has already been discussed on the linux-media list
in the past:

DEV_DISCONNECTED on others. In a matter of fact, DEV_MISCONFIGURED
were set only during the usb disconnect callback, with

Also, the alsa driver never checks if the device is present,

7528cd273e [media] cx231xx: Fix unregister logic
There are several weirdness at the unregister logic.

First of all, IR has a poll thread. This thread needs to be
removed, as it uses some resources associated to the main driver.
So, the driver needs to explicitly unregister the I2C client for
ir-kbd-i2c.

If, for some reason, the driver needs to wait for a close()
to happen, not all memories will be freed, because the free
logic were in the wrong place.

Also, v4l2_device_unregister() seems to be called too early,
as devices are still using it.

Finally, even with the device disconnected, there is one
USB function call that will still try to talk with it.

a116a05cb4 [media] cx231xx: fix crash after load/unload/load of module
The following sequence of commands was triggering a kernel crash in
cdev_get():

 modprobe cx231xx
 rmmod cx231xx
 modprobe cx231xx
 v4l2grab -n 1

The problem was that cx231xx_usb_disconnect() was not doing anything
because the test:

	if (!dev->udev)
		return;

was reached (i.e, dev->udev was NULL).

This is due to the fact that the 'dev' pointer placed as intfdata into
the usb_interface structure had the wrong value, because
cx231xx_probe() was doing the usb_set_intfdata() on the wrong
usb_interface structure. For some reason, cx231xx_probe() was doing
the following:

static int cx231xx_usb_probe(struct usb_interface *interface,
			     const struct usb_device_id *id)
{
        struct usb_interface *lif = NULL;
	[...]
        /* store the current interface */
        lif = interface;
	[...]
        /* store the interface 0 back */
        lif = udev->actconfig->interface[0];
	[...]
	usb_set_intfdata(lif, dev);
	[...]
	retval = v4l2_device_register(&interface->dev, &dev->v4l2_dev);
	[...]
}

So, the usb_set_intfdata() was done on udev->actconfig->interface[0]
and not on the 'interface' passed as argument to the ->probe() and
->disconnect() hooks. Later on, v4l2_device_register() was
initializing the intfdata of the correct usb_interface structure as a
pointer to the v4l2_device structure.

Upon unregistration, the ->disconnect() hook was getting the intfdata
of the usb_interface passed as argument... and casted it to a 'struct
cx231xx *' while it was in fact a 'struct v4l2_device *'.

The correct fix seems to just be to set the intfdata on the proper
interface from the beginning. Now, loading/unloading/reloading the
driver allows to use the device properly.

b247377ace [media] dvb: remove bogus modulation check
This code is wrong as I should have coded it as SYS_DVBC, instead of
SYS_DVBS & friends. Anyway, this check has other problems

1) it does some "magic" by assuming that all QAM modulations are below
  QAM_AUTO;

2) it checks modulation parameters only for one delivery system.
   Or the core should check invalid parameters for all delivery
   systems, or it should let the frontend drivers do it;

3) frontend drivers should already be checking for invalid parameters
   (most of them do it, anyway);

4) not all modulations are mapped at fe->ops.info.caps, so it is not
   even possible to check for the valid modulations inside the core
   for some delivery systems;

5) The core check is incomplete anyway: it only checks for a few
   parameters. If moved into the core other parameters like bandwidth
   and fec should also be checked;

6) 2nd gen DVB-C uses OFDM. So, that test would fail for it.

98ab8550ae [media] xc3028: fix center frequency calculation for DTV78 firmware
This patch replaces the previous one proposed in the thread "xc3028:
force reload of DTV7 firmware in VHF band with Zarlink demodulator",
at the linux-media@vger.kernel.org ML.

The problem is that the firmware DTV78 works fine in UHF band (8 MHz
bandwidth) but is not working at all in VHF band (7 MHz bandwidth).
Reading the comments inside the code, I figured out that the real
problem could be connected to the formula used to calculate the center
frequency offset in VHF band.

In fact, removing this adjustment fixes the problem:

		if ((priv->cur_fw.type & DTV78) && freq < 470000000)
			offset -= 500000;

This is coherent to what was implemented for the DTV7 firmware by an
Australian user:

		if (priv->cur_fw.type & DTV7)
			offset += 500000;

In the end, now the center frequency is the same for all firmwares
(DTV7, DTV8, DTV78) and doesn't depend on channel bandwidth.

The final code looks clean and simple, and there is no need for any
"magic" adjustment:

		if (priv->cur_fw.type & DTV6)
			offset = 1750000;
		else	/* DTV7 or DTV8 or DTV78 */
			offset = 2750000;

The VIDIOC_LOG_STATUS ioctl allows to dump the current status of a driver
to the kernel log. Currently this ioctl is only available at video device
nodes and the subdevs rely on the host driver to expose their core.log_status
operation to user space.

This patch adds VIDIOC_LOG_STATUS support at the sub-device nodes,
for standalone subdevs that expose their own /dev entry.
