If I implement a gpio chip driver built as module, and I want to use
gpiochip_request_own_desc(), how am I supposed to get desc ?

I understand that there is still gpio_to_desc(), but I would have thought
that
	desc = gpiochip_get_desc(chip, pin);
would be better than
	desc = gpio_to_desc(chip->base + pin);

Not that it makes much of a difference for me, just asking.

Thanks,
Guenter
