of_parse_coupled_regulator() returns the coupled regulator with its device reference incremented and regulator_resolve_coupling() stores it in coupling_desc.coupled_rdevs[]. regulator_remove_coupling() clears those pointers without dropping the references, so they are leaked when the couple is torn down. Release the reference of each coupled regulator while removing the coupling.
