This is part of the media-ci effort.

It is definitely not the most fun patches to do or review, but someone
has to do it :)

The whole idea is that we want to get as little warnings as possible
from the static analysers, after this patchset we almost achieve that.

It is only 2 trivial uvc patches, I can ask someone from my team to
review it if you want and trust them ;)

Regards!
