Subject: [PATCH v2 13/17] rcar-vin: refactor and fold in function after stall handling rework
Date: Wed, 24 May 2017 02:15:36 +0200 [thread overview]
Message-ID: <20170524001540.13613-14-niklas.soderlund@ragnatech.se> (raw)
In-Reply-To: <20170524001540.13613-1-niklas.soderlund@ragnatech.se>
From: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
With the driver stopping and starting the stream each time the driver is
stalled rvin_capture_off() can be folded in to the only caller.
Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
