As a second thought - do we need such a stub function at all? I guess
anyone who is actually adding a call to the
rohm_regulator_set_voltage_sel_restricted() helper should also have the
implementation selected. Failing to do so is probably indication of an
error. Compile testing could perhaps be an exception but this is
currently not supported.
Should I just drop the stub or make it inline? Am I overlooking something?
