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. Thierry
