This reads like a switch statement with a default: case to me.

This should just call list_voltage() to do the mapping into a voltage or
better yet should be converted into a get_voltage_sel() which will mean
that the core can call list_voltage() for you. Either way you save
duplicating the code to map from selector to voltage.
