There's no need to add planes to the atomic state. Remove the call to drm_atomic_add_affected_planes() from ast. On full modesets, the DRM helpers already add a CRTC's planes to the atomic state; see drm_atomic_helper_check_modeset(). There's no reason to call drm_atomic_add_affected_planes() unconditionally in the CRTC's atomic_check() in ast. It's also too late, as the atomic_check() of the added planes will not be called before the commit.
