Message-ID: <563BB8DF.7020908@users.sourceforge.net> Date: Thu, 5 Nov 2015 21:15:27 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Viresh Kumar <viresh.kumar@...aro.org>, linux-pm@...r.kernel.org Cc: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] CPPC-CPUFreq: Delete an unnecessary check before the function call "kfree" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Thu, 5 Nov 2015 21:10:29 +0100 The kfree() 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.
