Laurent Pinchart 47cc3cae30 media: uvcvideo: Don't expose unsupported formats to userspace ... [ Upstream commit 81f3affa19 ] When the uvcvideo driver encounters a format descriptor with an unknown format GUID, it creates a corresponding struct uvc_format instance with the fcc field set to 0. Since commit 50459f103e ("media: uvcvideo: Remove format descriptions"), the driver relies on the V4L2 core to provide the format description string, which the V4L2 core can't do without a valid 4CC. This triggers a WARN_ON. As a format with a zero 4CC can't be selected, it is unusable for applications. Ignore the format completely without creating a uvc_format instance, which fixes the warning.
