Subject: [PATCH v8 10/28] rcar-vin: do not reset crop and compose when setting format
Date: Wed, 29 Nov 2017 20:43:24 +0100	[thread overview]
Message-ID: <20171129194342.26239-11-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20171129194342.26239-1-niklas.soderlund+renesas@ragnatech.se>

It was a bad idea to reset the crop and compose settings when a new
format is set. This would overwrite any crop/compose set by s_select and
cause unexpected behaviors, remove it. Also fold the reset helper in to
the only remaining caller.
