CVE-2025-38044: debian linux — Fix

Description

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.
