Subject: [PATCH 1297/1795] media: rcar-vin: move media bus configuration to
struct rvin_dev
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Bus configuration will once the driver is extended to support Gen3
contain information not specific to only the directly connected parallel
subdevice. Move it to struct rvin_dev to show it's not always coupled
to the parallel subdevice.
