[PATCH 03/22] phy: phy-mvebu-sata: Add missing error check for devm_kzalloc

From: Kishon Vijay Abraham I
Date: Wed Sep 24 2014 - 09:56:30 EST

From: Peter Griffin <peter.griffin@xxxxxxxxxx>

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.
