From d865e573b8a4f30fbb74fa7666ca81e3132eb547 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 13 Jan 2016 09:18:55 -0500 Subject: audit: Delete unnecessary checks before two function calls The functions consume_skb() and kfree_skb() test whether their argument is NULL and then return immediately. Thus the tests around their calls are not needed. This issue was detected by using the Coccinelle software.
