Place drm_event_vblank in a new union that includes that and a bare drm_event structure. This will allow new members of that union to be added in the future without changing code related to the existing vbl event type. Assignments to the crtc_id field are now done when the event is allocated, rather than when delievered. This way, delivery doesn't need to have the crtc ID available. v2: * Remove 'dev' argument from create_vblank_event It wasn't being used anyways, and if we need it in the future, we can always get it from crtc->dev. * Check for MODESETTING before looking for crtc in queue_vblank_event UMS drivers will oops if we try to get a crtc, so make sure we're modesetting before we try to find a crtc_id to fill into the event.
