All these GPIO config variables are a mess. Drivers dependent on GENERIC_GPIO may also end up dependent on GPIOLIB, depending on the architecture. If the architecture sets ARCH_WANT_OPTIONAL_GPIOLIB then GPIOLIB is not automatically selected (except that some drivers do). Anyway - I see no reason why we should actually enable this driver, so I'll disable it instead. If you find any other drivers that require GPIOs then those should also be disabled in the top-level config. Ben.
