    drm: Reorganize drm_pending_event to support future event types [v2] · bd386e51
    Keith Packard authored
    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.
