The regulator API stubs itself out when disabled, but given that this is
just wrappers it's not clear what the tasteful thing would be here - it
should do the right thing because it will itself be built in terms of
the C stubs.  I don't know if Rust can sensibly stub things, or if
there's much percentage in that for a thin wrapper which does basically
nothing itself.
