Rob Clark 786813c343 drm/msm/mdp5: use __drm_atomic_helper_plane_duplicate_state() ... Somehow the helper was never retrofitted for mdp5. Which meant when plane_state->fence was added, it could get copied into new state in mdp5_plane_duplicate_state(). If an update to disable the plane (for example on rmfb) managed to sneak in after an nonblock update had swapped state, but before it was committed, we'd get a splat: WARNING: CPU: 1 PID: 69 at ../drivers/gpu/drm/drm_atomic_helper.c:1061 drm_atomic_helper_wait_for_fences+0xe0/0xf8 Modules linked in: CPU: 1 PID: 69 Comm: kworker/1:1 Tainted: G W 4.11.0-rc8+ #1187 Hardware name: Qualcomm Technologies, Inc.
