From 23ee0f192033ac6742fc179699d91336a000aef5 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 2 Jul 2018 13:47:08 +0100 Subject: pinctrl: actions: fix unsigned less than zero comparison The check to see if platform_get_irq failed is performed on the unsigned value of pctrl->irq[i] and the check is never true because an unsigned cannot be less than zero. Fix this by assinging the signed int ret to the return of platform_get_irq and checking ret instead.
