As I mentioned in my pull request to Linux I will be picking up the
Apple keyboard driver for this merge window even though it was not in
next (my fault).

I created and immutable branch for this change if you'd like to pull it
in so we do not duplicate commit and risk the conflicts (but I believe
git should resolve it either way).

Thanks.
