[PATCH 1/9] media: vim2m: Try to schedule a m2m device run on request submission

From: Paul Kocialkowski
Date: Fri Mar 09 2018 - 05:10:48 EST


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.
