Freeing the gpio is a little on the iffy side since you actually care
about keeping the value. Perhaps you can change this to
devm_gpio_request_one() and avoid the free? I was about to submit a
patch to do just that (since otherwise you run into trouble if you
ever defer the probe) but then ran across your patch.
Thanks!
