Comment 0 for bug 1791908

at each boot I see the messages:
10:34:47 kernel: uvcvideo: Failed to query (GET_INFO) UVC control 4 on unit 2: -32 (exp. 1).
10:34:47 kernel: uvcvideo: Failed to query (GET_INFO) UVC control 4 on unit 1: -32 (exp. 1).
10:34:46 kernel: uvcvideo: Failed to query (GET_INFO) UVC control 2 on unit 1: -32 (exp. 1).

this happen on a partition running Ubuntu 18.10 kernel 4.18.0-7-generic but not on the partition running Ubuntu 18.04 kernel 4.15.0-34 on same hardware

The integrated webcam works fine and i don't have other webcam connected.
