[PATCH] pinctrl-adi2: Use a signed return type for adi_gpio_irq_startup()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 19 Dec 2015 17:55:39 +0100

The return type "unsigned int" was used by the adi_gpio_irq_startup()
function despite of the aspect that it will eventually return a negative
error code.
Improve this implementation detail by deletion of the type modifier then.

This issue was detected by using the Coccinelle software.
