From: Markus Elfring Date: Wed, 4 Feb 2015 19:06:39 +0000 (+0100) Subject: hostap: Delete an unnecessary check before the function call "kfree" X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6f24fe305986afcb9eb2bde1031798b3b2ebf649;p=linux-beck.git 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.
