After fixing all of them we go down to:

Total for uvcvideo device /dev/media0: 8, Succeeded: 8, Failed: 0, Warnings: 0
Total for uvcvideo device /dev/video0: 54, Succeeded: 54, Failed: 0, Warnings: 3

Grand Total for uvcvideo device /dev/media0: 108, Succeeded: 108,
Failed: 0, Warnings: 3

With Hans patch we can also pass v4l2-compliance -s, but it is a WIP.
