If the kernel is built without regulator API support then the get,
release, enable and disable functions are stubbed out to always report
success.  If the kernel has been built with regulator support then
generally a fixed voltage regulator should be defined by the board.  The
expectation is that if the regulator API is of no use on a board since
there are no regulators set up then it'll be disabled in Kconfig.
