CVE-2025-38044

In the Linux kernel, the following vulnerability has been resolved:

media: cx231xx: set device_caps for 417

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.
