+Subject: [PATCH 720/773] drm/vc4: Ensure zpos is always initialised
+
+The compiler is warning that default_zpos can be used
+uninitialised as there is no default case to catch all plane
+types.
+No other plane types should ever be presented to vc4_fkms_plane_init,
+but add a default case regardless.
