We don't need to disable the regulator if enabling it failed (probably,
I haven't looked at the code).
I wasn't sure if ret would need to be cleaned up on failure, so I kept
it as it was before. I'll change it to a simple return if needed though.

Well chosen label names, btw. Very easy to review.
That was already there before I came. But yes, very nice choice of
names. :)
