Date: Tue, 18 Nov 2014 20:16:05 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: "David S. Miller" <davem@...emloft.net>, netdev@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Coccinelle <cocci@...teme.lip6.fr> Subject: [PATCH 1/1] net: pktgen: Deletion of an unnecessary check before the function call "proc_remove" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Tue, 18 Nov 2014 20:10:34 +0100 The proc_remove() 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.
