Updated: Only error is readbuffers now. I'll fix it and submit a v2
patch with 0 errors.
FYI, the fix for the readbuffers v4l2-compliance fail will be setting
v4l2_streamparm.capture.readbuffers to the minimum buffer value.
Thanks,

You added read() support, but did not add V4L2_CAP_READWRITE to
querycap.
The following errors are a knock-on effect of that since the driver
is still in read() mode so attempts to call REQBUFS will fail.
I should see if I can improve that in v4l2-compliance.

Hans
