From 98c01b19b85d8d87927e8cfa09c4a2a14add9ba2 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sat, 29 Jul 2017 21:07:07 +0300 Subject: pinctrl-st: fix of_irq_to_resource() result check of_irq_to_resource() has recently been fixed to return negative error #'s along with 0 in case of failure, however the ST driver still only regards 0 as failure indication -- fix it up.
