commit 77d84a6c17ae98194541ac16e8a9df748e4a0795 Author: Markus Elfring elfring@users.sourceforge.net Date: Sun Nov 15 08:04:43 2015 +0100

batman-adv: Delete unnecessary checks before the function call "kfree_skb"

The kfree_skb() function tests whether its argument is NULL and then returns immediately. Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.
