-Subject: [PATCH] drm: set is_master to 0 upon drm_new_set_master() failure
-
-When drm_new_set_master() fails, set is_master to 0, to prevent a
-possible NULL pointer deref.
-
-Here is a problematic flow: we check is_master in drm_is_current_master(),
-then proceed to call drm_lease_owner() passing master. If we do not restore
-is_master status when drm_new_set_master() fails, we may have a situation
-in which is_master will be 1 and master itself, NULL, leading to the deref
-of a NULL pointer in drm_lease_owner().
-
-This fixes the following OOPS, observed on an ArchLinux running a 4.19.2
-kernel:
