From 1f8de849cf8399ff287bab560d04df4515ec73c0 Mon Sep 17 00:00:00 2001 From: Peter Griffin Date: Fri, 15 Aug 2014 13:40:09 +0100 Subject: phy: phy-mvebu-sata: Add missing error check for devm_kzalloc Currently this driver is missing a check on the return value of devm_kzalloc, which would cause a NULL pointer dereference in a OOM situation. This patch adds the aformentioned missing check.
