Date: Wed, 24 Sep 2014 19:17:01 +0530 From: Kishon Vijay Abraham I <kishon@...com> To: <gregkh@...uxfoundation.org> CC: <kishon@...com>, <linux-kernel@...r.kernel.org> Subject: [PATCH 03/22] phy: phy-mvebu-sata: Add missing error check for devm_kzalloc From: Peter Griffin <peter.griffin@...aro.org> 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.
