[PATCH v2 0/2] media: uvcvideo: Automatically handle invalid uvc_versions

Posted by Ricardo Ribalda 2 weeks ago

This series changes the way we handle invalid uvc_versions. Instead of
just failing it will try to continue probing.

Now that we are at it, add a quirk to fix an Avermedia device affected
by this error.

Why keep using the quirk? Because I think it is more correct to handle
them that way and the quirk system can give us an idea of what vendors
are more respectful with the spec.

Thanks!
