In my computer I am getting this output for
v4l2-compliance -m /dev/media0 -a -f
Total for uvcvideo device /dev/media0: 8, Succeeded: 6, Failed: 2, Warnings: 0
Total for uvcvideo device /dev/video0: 54, Succeeded: 50, Failed: 4, Warnings: 2
Total for uvcvideo device /dev/video1: 46, Succeeded: 46, Failed: 0, Warnings: 0
Grand Total for uvcvideo device /dev/media0: 108, Succeeded: 102,
Failed: 6, Warnings: 2
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: 9
Total for uvcvideo device /dev/video1: 46, Succeeded: 46, Failed: 0, Warnings: 0
Grand Total for uvcvideo device /dev/media0: 108, Succeeded: 108,
Failed: 0, Warnings: 9
We are still not compliant with v4l2-compliance -s:
Streaming ioctls:
test read/write: OK (Not Supported)
test blocking wait: OK
fail: v4l2-test-buffers.cpp(1265):
node->streamon(q.g_type()) != EINVAL
test MMAP (no poll): FAIL
fail: v4l2-test-buffers.cpp(1265):
node->streamon(q.g_type()) != EINVAL
test MMAP (select): FAIL
fail: v4l2-test-buffers.cpp(1265):
node->streamon(q.g_type()) != EINVAL
test MMAP (epoll): FAIL
But fixing that will probably require a lot of changes in the driver
that are already implemented in the vb2 helpers. It is better to
continue Hans work on that:

Changelog v2 (Thanks to Hans and Laurent)
- Reimplement the CTRL_CLASS as a patch on queryctl
- Do not return -EIO for case 8
- Handle request bug and which_def multiclass in core
