[ Upstream commit 7be28bd7 ] 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.
