[media] dvb-usb: check for invalid length in ttusb_process_muxpack()
This patch is driven by a static checker warning.
The ttusb_process_muxpack() function is only called from
ttusb_process_frame(). Before calling, it verifies that len >= 2. The
problem is that len == 2 is not valid and would lead to an array
underflow.
Odd number values for len are also invalid and would lead to reading
past the end of the array.

[media] winbond-cir: only enable higher sample resolution if needed
A sample resolution of 2us generates more than 300 interrupts per key
and this resolution is not needed unless carrier reports are enabled.
Revert to a resolution of 10us unless carrier reports are needed. This
generates up to a fifth of the interrupts.

[media] ARM: davinci: da850 evm: pass platform data for adv7343 encoder
Without this patch the adv7343 encoder was being set to default
configuration which caused display not to work on this board.
This patch passes the necessary platform data required for adv7343
encoder to work on da850 evm.

[media] media: adv7343: accept configuration through platform data
The current code was implemented with some default configurations,
this default configuration works on board and doesn't work on other.
This patch accepts the configuration through platform data and configures
the encoder depending on the data passed.

[media] tm6000: fix querycap and input/tuner compliance issues
- add device_caps support
- fix bus_info
- fix numerous tuner-related problems due to incorrect tests
and setting v4l2_tuner fields to wrong values.
- remove (audio) input support from the radio: it doesn't belong
there. This also fixed a nasty issue where opening the radio
would set dev->input to 5 for no good reason. This was never
set back to a valid TV input after closing the radio device,
thus leaving it at 5 which is out of bounds of the vinput
card array.

[media] meye: convert to the control framework
Convert the meye driver to the control framework. Some private controls
have been replaced with standardized controls (SHARPNESS and JPEGQUAL).
The AGC control looks like it can be replaced by the AUTOGAIN control, but
it isn't a boolean so I do not know how to interpret it.
The FRAMERATE control looks like it can be replaced by S_PARM, but again,
without knowing how to interpret it I decided to leave it alone.

[media] videobuf2: don't return POLLERR when only polling for events
If you only poll for events, then vb2_poll will return POLLPRI | POLLERR if
no streaming is in progress. That's not right, it's perfectly valid to
poll just for events.
