[media] adv7175: Make use of media bus pixel codes

The ADV7175A/ADV7176A can operate in either 8-bit or 16-bit YCrCb mode.

* 8-Bit YCrCb Mode
This default mode accepts multiplexed YCrCb inputs through
the P7-P0 pixel inputs. The inputs follow the sequence Cb0, Y0
Cr0, Y1 Cb1, Y2, etc. The Y, Cb and Cr data are input on a
rising clock edge.

* 16-Bit YCrCb Mode
This mode accepts Y inputs through the P7–P0 pixel inputs and
multiplexed CrCb inputs through the P15–P8 pixel inputs. The
data is loaded on every second rising edge of CLOCK. The inputs
follow the sequence Cb0, Y0 Cr0, Y1 Cb1, Y2, etc.

[media] em28xx: implement VIDIOC_ENUM_FRAMESIZES

Pidgin uses gstreamer (and libv4l) to work. Without implementing this ioctl,
it won't detect properly the size range, and driver will fail.

So, this patch is required, in order to use an em27xx webcam, like
Silvercrest.

The pigdin/gstreamer/libv4l needs to be fixed, as it shouldn't assume
that all drivers will implement this optional ioctl, but, at least now,
devices with em28xx have a better chance of working with pidgin.

[media] cx23885: Avoid incorrect error handling and reporting

Previous driver over-reported errors and stopped the video fifo
(causing video to stop) if 1) A risc error occured 2) The risc processor
detected that it has missing lines in the video frame 3) The risc fifo
is about to overflow.

The previous driver reported all three of these cases as risc errors
when this is technically not correct. So, the function was cleaned up.

1. Ensure that risc opcode related errors are correctly shown as such,
   and not overly reported for non-risc-opcode cases.
2. Ensure that line sync and overflow errors are not reported as opcode errors.
3. Ensure that only the risc-op-code case can stop the fifo and dump channel
   / risc processor information.

The net result is that if video becomes unstable, cable disconnect, this will
not trigger a stop of the video firmware (due to missing lines errors).

[media] s5p-tv: hdmi: use DVI mode

Current version of the driver does not support HDMI features
not present in DVI standard. Therefore DVI mode is used to
keep compatibility with DVI devices.

[media] em28xx: replug locking cleanup

Simplifies the locking by moving the em28xx_init_extension() call until
em28xx_usb_probe() has finished with the dev->lock mutex. It therefore
makes the second and subsequent "plugging" events logically identical to
the first "plugging" event when the em28xx-dvb and em28xx-alsa modules
must be loaded (i.e. registered).

Basically, em28xx_usb_probe() requests that em28xx-dvb be loaded and
also triggers udev to initialise the V4L2 devices. These two events are
serialised by the dev->lock mutex but the order that they happen in is
undefined. But this has always been the case anyway.

[media] em28xx: fix deadlock when unplugging and replugging a DVB adapter

This fixes the deadlock that occurs with either multiple PCTV 290e adapters or when a single PCTV 290e adapter is replugged.

For DVB devices, the device lock must now *not* be held when adding/removing either a device or an extension to the respective lists. (Because em28xx_init_dvb() will want to take the lock instead).

Conversely, for Audio-Only devices, the device lock *must* be held when adding/removing either a device or an extension to the respective lists.

[media] em28xx: fix race on disconnect

This patch closes the race on the device and extension lists at USB disconnect
time. Previously, the device was removed from the device list during
em28xx_release_resources(), and then passed to the em28xx_close_extension()
function so that all extensions could run their fini() operations. However, this
left a (brief, theoretical, highly unlikely ;-)) window between these two calls
during which a new module could call em28xx_register_extension(). The result
would have been that the em28xx_usb_disconnect() function would also have passed
the device to the new extension's fini() function, despite never having called
the extension's init() function.

This patch also restores em28xx_close_extension()'s symmetry with
em28xx_init_extension(), and establishes the property that every device in the
device list must have been initialised for every extension in the extension list.
