[Xen-devel] [PATCH v2 3/4] drm/cirrus: Let DRM core send VBLANK events
In drm_atomic_helper_fake_vblank(), the DRM core sends out VBLANK
events if struct drm_crtc_state.no_vblank is enabled. Replace cirrus'
VBLANK events with the DRM core's functionality.
v2:
* set struct_drm_crtc_state.no_vblank in cirrus_pipe_check()
