I still wasn't happy with this approach, so I bugged Arnd and we
discussed some options. So, I think I've got a better solution that
doesn't change the signature of of_xlate. Instead it allows of_xlate
to return an error code and still have multiple banks referring to the
I've just posted the series. Can you try it out and make sure it
works for you?
