Lucas Stach 83f31c8a5f [media] coda: adjust sequence offset after unexpected decoded frame
If userspace doesn't properly separate the bitstream input into
individual frames (which may happen for example on slightly
corrupted streams) the CODA hardware may decode more frames
than we expect. We already log an error in this case, but it's
also necessary to adjust the sequence offset. Otherwise we
spam the log with a sequence number mismatch on every frame
frame after the unexpected one.

Nicolas Dufresne 1b880ef62c [media] s5p-mfc-v6+: Use display_delay_enable CID
The MFC driver has two controls, DISPLAY_DELAY and DISPLAY_DELAY_ENABLE
that allow forcing the decoder to return a decoded frame sooner
regardless of the order. The added support for firmware version 6 and
higher was not taking into account the DISPLAY_DELAY_ENABLE boolean.
Instead it had a comment stating that DISPLAY_DELAY should be set to a
negative value to disable it. This is not possible since the control
range is from 0 to 65535. This feature was also supposed to be disabled
by default in order to produce frames in display order.

Michael Ira Krufky 27f7ef7ca9 [media] lgdt3305: add support for fixed tp clock mode
Add support for controlling TP clock mode for VSB and QAM annex-B/C mode.
Gated clock mode is the default value, and does not support QAM annex-C.
The patch enables setting this control to fixed clock mode.
