| |
4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
commit 4086d90cffb8f48400d51fbab575fe50458512e3 upstream.
All atomic state should be cleared when drm_modeset_backoff() is called, because it drops all locks and the state becomes invalid.
The call to drm_atomic_state_clear was missing in atomic_remove_fb, so add the missing call there.
