That is not the issue. The real issue is h3xxx using those gpio's without
previously calling gpio_request.
Really? But that wasn't done before this patch either.
It is basically OK to use the gpio_* functions before or
without requesting the GPIOs, it won't look nice but it
works.
Unfortunately sa1100 driver doesn't have a
good place to request gpios. When faced this problem during locomo
refactoring, I ended up with the following piece of code:

Russell, Linus, what do you think about the previous solution?
That looks OK but is that really the problem?
I have reworked h3xxx GPIO handling to (hopefully) not to cause the
problem. I have sent the patches yesterday.
Linus, Could you please check if both series work (and make sense to you)?
