Author: Markus Elfring <elfring@users.sourceforge.net> 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.
