From 9fee1faf602891e530f5ffec3a7dfe2e3d00ad97 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 7 Mar 2022 17:13:49 +0300 Subject: [PATCH] mt76: mt7915: check for devm_pinctrl_get() failure If devm_pinctrl_get() fails then it leads to an error pointer dereference. Add a check to prevent that.
