Note that the 6 in the third argument of memset appears to represent
an ethernet address size (ETH_ALEN).

On built-in kernels this warning will always splat as this is part
of the module init. Fix that by shifting the PAT requirement check
out under the code that does the "quasi-probe" for the device. This
device driver relies on an existing driver to find its own devices,
it looks for that device driver and its own found devices, then
uses driver_for_each_device() to try to see if it can probe each of
those devices as a frambuffer device with ivtvfb_init_card(). We
tuck the PAT requiremenet check then on the ivtvfb_init_card()
call making the check at least require an ivtv device present
before complaining.

I noticed certain cards are currently under MEDIA_ANALOG_TV_SUPPORT
but it seems they are frame grabbers (with CVBS, Svideo etc. inputs)
rather than TV receivers (with analog TV tuners).

MEDIA_CAMERA_SUPPORT maybe isn't the best name (only "meye" driver seems
to drive a real camera in a laptop) but it at least doesn't select the
TUNERs.

Perhaps the following patch would make sense.

Current code assigns 0 to variable 'err', which makes mantis_dma_init()
to return success even if mantis_alloc_buffers() fails.

Fix it by checking the return value from mantis_alloc_buffers() and
propagating it in the case of error.

To compile videobuf2-core as a module, the vb2_* tracepoints must be
exported from the videodev module. Instead of exporting vb2 tracepoint
symbols from v4l2-ioctl.c, move the tracepoint generation into a separate
file. This patch fixes the following build error in the modpost stage,
introduced by 2091f518 ("[media] videobuf2: add trace events"):

Using adv7611_read_cable_det() for ADV7612 means that full
support for '.max_port = ADV7604_PAD_HDMI_PORT_B,' isn't available
due to the need for multiple port reads to determine cable detection,
and an agreed mechanism for communicating the separate statuses.

This patch replaces adv7611_read_cable_det() with a functionally
identical copy, commented appropriately.

Earlier submissions [leading to commit 8331d30b] also set .cp_csc,
which is used in a cp_read() call within adv76xx_log_status().
