All the other state related functions are named using the pattern drm_atomic_get_(old|new)_$object_state. Moreover, we already have a drm_atomic_get_new_connector_for_encoder function that does return a drm_connector, so I think we should make it consistent there and call it drm_atomic_get_new_crtc_state_for_bridge Maxime
