From 32260d94408c553dca4ce54104edf79941a27536 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 12 Mar 2012 08:33:10 -0700 Subject: [PATCH] hwmon: (w83627ehf) Fix memory leak in probe function The driver probe function leaked memory if creating the cpu0_vid attribute file failed. Fix by converting the driver to use devm_kzalloc.
