If later, there is an\nallocation failure or another failure at setup_out_fence(), that event\nwill not have base.fence set and it will not be released at\ncomplete_signaling().\n\nRelease the event and set crtc_state->event to NULL just like in the\nDRM_MODE_PAGE_FLIP_EVENT case when there is a failure at\ndrm_event_reserve_init().
