Maybe instead of exposing such a dangerous function, wrap it in something like

drm_atomic_crtc_state_for_each_plane_state, which returns either get_current_plane_state or plane->state?

The only times this function is used is when iterating over all plane states a anyway, and it would be useful for i915 too.
