The indentation here is odd and we probably ought to complain if someone
tries to set a current constarint on a regulator that doesn't support
the operation, if only to avoid surprises later on when the limits don't
take effect.

Why is this conditional on the existing setting? Just apply the
constraint.

Missing blank.
