Subject: [PATCH 1/4] rcar-vin: Rename rectangle holding holding the video source information
Date: Fri,  5 Jul 2019 06:55:54 +0200	[thread overview]
Message-ID: <20190705045557.25463-2-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <20190705045557.25463-1-niklas.soderlund+renesas@ragnatech.se>

The variable to hold the video source information dimensions was poorly
named 'source'. This is confusing as a lot of other members of struts
share the same name with different purposes, rename it src_rect in
preparation of refactoring code.
