Ah, sorry - I hadn't realised this patch had the cleanup code.  This
needs a bit of an update - as I said for one of the earlier patches we
need to reference count to make sure we only free the GPIO when it has
no users.  With this patch we will free the GPIO when the first
regulator to use it is freed which might mean other regulators are still
using it.
