Re: [RFC PATCH 0/1] media: uvcvideo: reset interface on bulk stream stop

On the NVIDIA xHCI host controller, I see the former.

After each stop/start cycle, uvcvideo reports one -71 completion error,
and only the first frame is broken. Streaming then continues normally. I
do not see multiple transaction errors or a complete functional failure.

With 25e531b422dc applied, the -71 completion error no longer appears in
the same test.

Thanks,
Henry
