    drm - Fix drm_modeset_unlock() panic
    
    * Fix a bug in drm_modeset_lock() which sometimes improperly returned
      success when the ww mutex actually failed.
    
    * This should fix a panic in the related drm_modeset_unlock() code
      that complains about unlocking a lock that isn't being held.
