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.
