Exactly what kind of drivers are we looking to fix here? These might
be the possible cases:
- We are checking 'regulator pointer' before calling and don't need to
handle anything there..
- drivers depend on CONFIG_REGULATOR and so again we don't need
to handle anything
- None of above are true and drivers aren't checking return value of
regulator_set_voltage()
OR
They are checking it and failing when it failed..

What do we want to do in these cases?
