4 Subject: [PATCH] drm/vc4: Ensure zpos is always initialised
5
6 The compiler is warning that default_zpos can be used
7 uninitialised as there is no default case to catch all plane
8 types.
9 No other plane types should ever be presented to vc4_fkms_plane_init,
10 but add a default case regardless.
