I looked over the code like 5 times and I can't see it touching any
gpiolib internals anymore, but maybe I'm still wrong?

Normally GPIO drivers should get all symbols it needs from
<linux/gpio/driver.h> and "gpiolib.h" is not something drivers
should include.

Anyways I will get to know from compile tests if I'm wrong.
