Message-ID: <54D0D6CC.1050708@users.sourceforge.net> Date: Tue, 03 Feb 2015 15:10:20 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Mauro Carvalho Chehab <mchehab@....samsung.com>, Olli Salonen <olli.salonen@....fi>, linux-media@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] [media] sp2: Delete an unnecessary check before the function call "kfree" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Tue, 3 Feb 2015 15:05:26 +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.
