If it was a simple search/replace, why wouldn't have been done already?

Again, you need to prove why this is ok at all.  pci_enable_msi()
shouldn't be used in new drivers, but what's wrong with it being in
existing drivers?  Especially in ones that you can't test to verify it
still works after changing the code?
