From 49af64e6b52208219d008cd445ca09c07a965105 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 6 May 2017 10:23:59 +0200 Subject: [PATCH] pinctrl: imx: Check for memory allocation failure If 'devm_kzalloc' fails, a NULL pointer will be dereferenced. Return -ENOMEM instead, as done for the other memory allocation just a few lines below. BTW, change the 'devm_kzalloc' into a 'devm_kcalloc'.
