ps- This will end up conflicting with my patch which moves that hunk
to a helper function, and also allocates the same hwprobe bit [1].
The fixup is very straightforward for a human, so the ordering isn't a big
deal either way. But I thought I'd give you a heads up so you weren't
surprised if someone mentioned it.
