Ran the most recent version from git master, got a total of 6 fails, 4
of which are probably easy fixes:

Changed the relevant code to:
usb_make_path(sur40->usbdev, cap->bus_info, sizeof(cap->bus_info));

Now returning -EINVAL when S_INPUT called with input != 0.

Setting colorspace in v4l2_pix_format to V4L2_COLORSPACE_SRGB.

Don't know how to fix this - does this mean VIDIOC_G/S_PRIORITY _must_
be implemented?

Also not clear how to fix this one.
Could you give some hints on the last two?
Thanks & best regards, Florian
