Subject: [PATCH v1 0/8] [RESEND] [PATCH 0/8] uvcvideo: Fixes for hw timestamping

Add some fixes for fixing hw timestamp on some Logitech and Sunplus
cameras. The issues have been previously reported to the manufacturers.

Also include a patch to fix the current hw timestamping logic for ANY
uvc 1.5 model running at under 16 fps.
