Subject[PATCH v2] thermal: Exynos: Deletion of unnecessary checks before two function calls
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 21 Nov 2014 17:11:49 +0100

The functions cpufreq_cooling_unregister() and thermal_zone_device_unregister()
test whether their argument is NULL and then return immediately.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
