Subject: [PATCH AUTOSEL 5.4 34/79] media: cx231xx: set device_caps for 417

From: Hans Verkuil <hverkuil@...all.nl>

[ Upstream commit a79efc44b51432490538a55b9753a721f7d3ea42 ]

The video_device for the MPEG encoder did not set device_caps.

Add this, otherwise the video device can't be registered (you get a
WARN_ON instead).

Not seen before since currently 417 support is disabled, but I found
this while experimenting with it.
