Subject: [PATCH] ti-soc-thermal: Delete an unnecessary check before the function call "cpufreq_cooling_unregister"
Date: Tue, 03 Feb 2015 11:21:14 +0100 [thread overview]
Message-ID: <54D0A11A.4070906@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>
From: Markus Elfring <elfring@users.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.
