Hm? I think the hogged pins are the *only* pins we can
reliably release when unloading the driver, look:

void pinctrl_unregister(struct pinctrl_dev *pctldev)
{
(...)
if (!IS_ERR(pctldev->p))
pinctrl_put(pctldev->p);

That releases all hogged pinctrl handles when unloading
a pinctrl driver.

Yours,
Linus Walleij
