Subject: [PATCH] ti-soc-thermal: Delete an unnecessary check before the function
 call "cpufreq_cooling_unregister"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 3 Feb 2015 11:15:14 +0100

The cpufreq_cooling_unregister() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
