If we ever hit bugs in our readout code we may have set plane_state->visible without setting a fb/crtc. Our code implicitly assumes that plane_state->visible is only true when both are set, so we will either null deref in intel_fbc_choose_crtc() or do something bad during the actual commit which cares even more.
