This patch series converts cx18 to vb2. It also fixes a number of
compliance issues.
The first two patches fix core bugs that only appear with a somewhat weird
driver like cx18: video0 only supports read() but streaming ioctls were
incorrectly enabled in the core; also vb2_fop_read had an ownership issue in
case vb2_read would return an error.
cx18 now passes the v4l2-compliance tests.
As usual, the vb2 conversion patch is pretty much unreviewable. It's
impossible to do an incremental vb2 conversion, it's all or nothing.
Regards,
Hans
