If the regulator is not used in the system then why is the driver
getting as far as trying to register it?  Surely this is a system
configuration error?  This all sounds like some problem with either the
system integration or the driver which is causing it to try to register
the regulator needlessly - you should be fixing that problem, not adding
ifdefs.  I'm still unclear on exactly what the issue is so it's hard to
say exactly what the best way forwards is.
