Applied, thanks. Note that I dropped the part about adding the GPIOLIB
dependency because that had been attempted previously to fix this, but
it causes recursive dependencies on PowerPC (ppc64_defconfig). I don't
know of a way to untangle those (I tried and failed miserably), so I
think adding the include is really as good as it'll get.
