From 6f24fe305986afcb9eb2bde1031798b3b2ebf649 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 4 Feb 2015 20:06:39 +0100 Subject: [PATCH] hostap: Delete an unnecessary check before the function call "kfree" The kfree() 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.
