The priv field of struct v4l2_pix_format shouldn't be set by drivers,
it's set by the v4l2 core instead to V4L2_PIX_FMT_PRIV_MAGIC.
Drop this from the few media drivers that still do this.
Note that the gspca patch is slightly more involved since some of the
sub-gspca drivers use the priv field internally.

Define struct cec_connector_info in media/cec.h and define
CEC_CAP_CONNECTOR_INFO. In a later patch this will be moved to
uapi/linux/cec.h.
The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but
cec_allocate_adapter() will remove it again until the public API
for this can be enabled once all drm drivers wire this up correctly.
Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions,
which are needed by drm drivers to fill in the cec_connector info
based on a drm_connector.
The cec_notifier_(un)register and cec_register_cec_notifier
prototypes were moved from cec-notifier.h to cec.h since cec.h no longer
includes cec-notifier.h. These headers included each other before,
which caused various problems.
Due to these changes the seco-cec driver was changed as well: it
should include cec-notifier.h, not cec.h.

If the first buffer contains only headers, the sequence initialization
command fails. On CodaHx4 the buffer must be padded to at least 512
bytes, on CODA960 it seems to be enough to just repeat the sequence and
extension headers (MPEG-2) or the VOS and VO headers (MPEG-4) once for
for sequence initialization to succeed without further bitstream data.
On CodaHx4 the headers can be repeated multiple times until the 512 byte
mark is reached.
A similar issue was solved for h.264 by padding with a filler NAL in
commit 0eef89403e ("[media] coda: pad first h.264 buffer to 512
bytes").
