From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Fri, 26 Jun 2015 16:10:54 +0200 Subject: [PATCH] fs-ext4 crypto: Delete an unnecessary check before the function call "key_put" 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.
