From 4086d90cffb8f48400d51fbab575fe50458512e3 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Thu, 29 Jun 2017 13:59:54 +0200 Subject: [PATCH] drm/atomic: Add missing drm_atomic_state_clear to atomic_remove_fb 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.
