Subject: [PATCH] keys: Delete an unnecessary check before the function call
"key_put"
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 26 Jun 2015 16:10:54 +0200
The key_put() 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.
