From: Maarten Lankhorst Date: Thu, 29 Jun 2017 11:59:54 +0000 (+0200) Subject: drm/atomic: Add missing drm_atomic_state_clear to atomic_remove_fb X-Git-Tag: v4.13-rc1~45^2~1^2~1 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=4086d90cffb8f48400d51fbab575fe50458512e3;p=linux.git 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.
