    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
    same gpio_chip.

    I've just posted the series. Can you try it out and make sure it
    works for you?
