Message-Id: <1408106416-19044-3-git-send-email-peter.griffin@linaro.org> Date: Fri, 15 Aug 2014 13:40:09 +0100 From: Peter Griffin <peter.griffin@...aro.org> To: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, kishon@...com, kgene.kim@...sung.com, maxime.ripard@...e-electrons.com, linux-samsung-soc@...r.kernel.org Cc: peter.griffin@...aro.org, patches@...aro.org, lee.jones@...aro.org Subject: [PATCH 2/9] 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.
