Whatever - I don't think the particular code makes any practical
difference.  We would need to audit existing users who don't have a
REGULATOR dependency for breakage though.

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..

I'm not sure what you mean by this.

- 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?

Well, we would need to look at what the drivers were doing and figure
out something sensible - it really depends why they're trying to set the
regulator and what would happen if it doesn't work.  For drivers that
ignore the return value they won't be affected anyway.
