This doesn't look right. You already have || buf-state ==
MX2_STATE_ACTIVE above, so, this latter condition is never entered?

to buffers being written when they are not ready.
It can be easily checked enabling DEBUG features of the driver.
This series migrate the driver to videobuf2 and provide an
additional discard queue to make sure all the events are
