So ... we're using %d here and %u in acpiphp. Obviously we don't expect
to get a number above 2 billion, but I think if we do have some utterly
bogus firmware that gives us a number above 2 billion, printing a
positive number is a better user experience than a negative number.

We clearly have a common pattern here where hotplug drivers have a
number insteaqd of a name (I would venture this is the most common).
Maybe we need a common helper? I think this is a subject for the
long-term todo list, not something that needs to be addressed in the
context of this patch series.
