From 5fcdc9d9816266c575ef21586327ba04d7db5c2c Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Wed, 21 Feb 2018 16:23:31 +0100 Subject: drm/atomic: Call ww_acquire_done after drm_modeset_lock_all After we acquired all generic modeset locks in drm_modeset_lock_all, it's unsafe acquire any other so just mark acquisition as done. Atomic drivers shouldn't use drm_modeset_lock_all.
