/**

 * 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.
