drivers/gpu/drm/drm_plane_helper.c: In function 'drm_primary_helper_update':
drivers/gpu/drm/drm_plane_helper.c:113:32: error: 'visible' is used
uninitialized [-Werror=uninitialized]
113 | struct drm_plane_state plane_state = {
| ^~~~~~~~~~~
drivers/gpu/drm/drm_plane_helper.c:178:14: note: 'visible' was declared here
178 | bool visible;
| ^~~~~~~
cc1: all warnings being treated as errors
visible is an output, not an input. in practice this use might turn out
OK but it's still UB.
