Given the intent behind gpiod_get_optional() and friends it does not make sense to return -ENOSYS when GPIOLIB is disabled: the driver is expected to work just fine without gpio so let's behave as if gpio was not found. Otherwise we have to special-case -ENOSYS in drivers. Note that there was objection that someone might forget to enable GPIOLIB when dealing with a platform that has device that actually specifies optional gpio and we'll break it. I find this unconvincing as that would have to be the *only GPIO* in the system, which is extremely unlikely.
