Date: Wed, 04 Feb 2015 13:00:46 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: netdev@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] net: fec: Delete unnecessary checks before the function call "kfree" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Wed, 4 Feb 2015 12:56:42 +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.
