This proposal seemingly doesn't work. If you disable monitoring of a regulator,
and no other regulators are being monitored at that point, then GP_FB2 will no
longer be asserted and you have the same issue. What's more this patch impacts
all users and there's no means to re-enable monitoring. Certainly in the current
state this isn't a valid change.

What exactly is the problem you're attempting to resolve through this patch?
