Subject: [PATCH 02/16] media: vimc: Remove unnecessary stream check
Date:   Fri, 15 Mar 2019 13:43:45 -0300
Message-Id: <20190315164359.626-3-andrealmeid@collabora.com>

Precedence: bulk

Since V4L2 already checks if the stream is running (and avoid starting
it twice), remove the check at subdevices.
