[media] cx88: Fix regression: CX88_AUDIO_WM8775 can't be 0

Cards using the wm8775 specify that in their card struct. Those that do not
use it leave the audio_chip field to 0. Unfortunately, the CX88_AUDIO_WM8775
enum is 0 as well, so boards that do not have the wm8775 still try to load
and use that driver. Change it to 1 to fix this.
This regression was introduced in commit facd23664f1d63c33fbc6da52261c8548ed3fbd4.

free_buff_list and rec_buff_list are initialized in the middle of hdpvr_probe(),
but if something bad happens before that, error handling code calls hdpvr_delete(),

[media] s5p-g2d: Fix registration failure

Commit 1c1d86a1ea ("[media] v4l2: always require v4l2_dev,

It converted most of the drivers using the parent field of video_device
to v4l2_dev field. G2D driver did not set the parent field. Hence it got
left out. Without this patch we get the following boot warning and G2D
driver fails to register the video device.

[media] v4l2-dv-timings: fix CVT calculation

This patch fixes two errors that caused incorrect format detections:
The first bug is in the calculation of the vertical backporch: the combined
period of vsync and backporch must *exceed* a certain minimum value, and not
be equal to it.
The second bug is a rounding error in the reduced blanking calculation:
expand the ideal_duty_cylce to be in parts per ten thousand to avoid
rounding errors.

[media] v4l2-mem2mem: clear m2m context from job_queue before ctx streamoff

When streamoff is called on the context and the context
is added to the job_queue,
1] sometimes device_run receives the empty vb2 buffers (as
   v4l2_m2m_streamoff is dropping the ready queue).
2] sometimes v4l2_m2m_job_finish may not succeed as the m2m_dev->curr_ctx
   is made NULL in the v4l2_m2m_streamoff()
The above points may stop the execution of the other queued contexts.
This patch makes sure that before streamoff is executed on any context,
that context should "not be running" or "not queued" in the job_queue.
1] If the current context is running, then abort job will be called.
2] If the current context is queued, then the context will be removed from
   the job_queue.

[media] cx23885: Add DTV support for Mygica X8502/X8507 boards

Those boards were missing the ISDB-T support.
Most of the work on this patch were done by Alfredo.
My work here were to port this patch from Kernel 3.2 to upstream,
fix the issue caused by the set_frontend bad hook, and add the
Kconfig bits.
Tested on a X8502 board rebranded as:
"Leadership - Placa PCI-e de Captura de Vídeo Híbrida" - product code 3800.

[media] cx23885-dvb: use a better approach to hook set_frontend

When the frontend drivers got converted to DVBv5 API, the original
hook that tracked when a frontend is set got removed, being replaced
by an approach that would use the gate control. That doesn't work
fine with some boards. Also, the code were called more times than
desired.
Replace it by a logic that will hook the dvb set_frontend ops,
with works with both DVBv3 and DVBv5 calls.
Tested on a Mygica X8502 OEM board.

[media] introduce gspca-stk1135: Syntek STK1135 driver

Hello,
this is a new gspca driver for Syntek STK1135 webcams. The code is completely
new, but register values are based on Syntekdriver (stk11xx) by Nicolas VIVIEN
(http://syntekdriver.sourceforge.net).
Only one webcam type is supported now - vendor 0x174f, device 0x6a31.
It's Asus F5RL laptop flippable webcam with MT9M112.
The camera works better than in Windows - initializes much faster and
provides more resolutions (the sensor can do almost any resolution - just
add it to the stk1135_modes[] - could this feature be somehow used by
applications to avoid SW scaling?).
Autoflip works too - when the camera is flipped around, the image is flipped
automatically.
