Message-ID: <56478B2A.6030808@users.sourceforge.net> Date: Sat, 14 Nov 2015 20:27:38 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Alexander Aring <alex.aring@...il.com>, "David S. Miller" <davem@...emloft.net>, linux-wpan@...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] mac802154: Delete an unnecessary check before the function call "kfree_skb" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Sat, 14 Nov 2015 20:22:41 +0100 The kfree_skb() 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.
