Subject: [PATCH] drm/vc4: Ensure zpos is always initialised
|
2019-07-31 16:23:26 +00:00
|
|
|
|
|
|
|
|
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.
|
|
|
