Subject: [PATCH 1/9] media: vim2m: Try to schedule a m2m device run on request submission
Date: Fri, 9 Mar 2018 11:09:25 +0100 [thread overview]
Message-ID: <20180309100933.15922-2-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20180309100933.15922-1-paul.kocialkowski@bootlin.com>
In the most basic use scenario, where only one output and one capture
buffers are queued and the request is submitted, there is no provision
to try to schedule a m2m device run.
This adds the appropriate call to the vim2m_request_submit so that it
can start in that scenario.
