Subject: drm: rcar-du: Embed rcar_du_planes structure into rcar_du_group
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=99caede11d84af4c0a16fd07f7d7ce9de94f6109;p=linux-beck.git

drm: rcar-du: Embed rcar_du_planes structure into rcar_du_group

The rcar_du_planes structure contains a single field and is only
instantiated in the rcar_du_group structure. Embed it directly and
remove the rcar_du_planes structure.
