* drm_atomic_crtc_needs_modeset - compute combined modeset need
* @state: &drm_crtc_state for the CRTC
*
* To give drivers flexibility struct &drm_crtc_state has 3 booleans to track
* whether the state CRTC changed enough to need a full modeset cycle:
* connectors_changed, mode_changed and active_change. This helper simply
* combines these three to compute the overall need for a modeset for @state.
