The only issue I can see is that this one doesn't check _EJ0. Unless
that's done, you'll (on some hardware) evaluate _STA on the bay itself
rather than the device within the bay, which leads to confusion as to
whether the device has been inserted. Other than that, looks good.
Jeff's sent my patch to Linus, so can you redo this on top and I'll sign
it off?
