[PATCH v3 1/4] v4l2-mem2mem: Avoid v4l2_m2m_prepare_buf from scheduling a job

[ezequiel at collabora.com (Ezequiel Garcia)]

There is no need for v4l2_m2m_prepare_buf to try to schedule a job,
as it only prepares a buffer, but does not queue or changes the
state of the queue.

Remove the call to v4l2_m2m_try_schedule from v4l2_m2m_prepare_buf.
