Even though we mostly use GPIO descriptors internally we still use gpio_request_one() to request so we need to pair that with gpio_free() to release the GPIO.
This doesn't explain the reason... I see the current GPIO code doing this:
void gpio_free(unsigned gpio) { gpiod_free(gpio_to_desc(gpio)); } EXPORT_SYMBOL_GPL(gpio_free);
Huh, good point (though it still seems a bit neater to match up the request and release functions I guess). Linus?
