Subject[PATCH] ieee802154-atusb: Delete an unnecessary check before the function call "kfree_skb"
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 16 Nov 2015 13:50:23 +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.
