Date: Thu, 20 Nov 2014 16:16:16 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Jan Dumon <j.dumon@...ion.com>, linux-usb@...r.kernel.org, netdev@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH 1/1] net: USB: Deletion of unnecessary checks before the function call "kfree" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Thu, 20 Nov 2014 16:11:56 +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.
