From 97bf73762fed743291bb7e572aa659374990b93d Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 27 Dec 2020 21:18:26 +0100 Subject: [PATCH] pinctrl: mediatek: correct error handling If no GPIO controller is found, the return value should not depend on a random value on the stack. Initialize variable ret. The problem was indicated by cppcheck.
