Subject: [PATCH v3 7/8] rcar-vin: Fold rvin_initialize_device() into rvin_open()
Date: Thu, 13 Jun 2019 01:45:46 +0200	[thread overview]
Message-ID: <20190612234547.14486-8-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20190612234547.14486-1-niklas.soderlund+renesas@ragnatech.se>

The function no longer serve a purpose as most tasks it performed have
been refactored, fold what remains of it into the only caller. While at
it add error checking for v4l2_ctrl_handler_setup().
