[PATCH 1/1] configfs: Deletion of unnecessary checks before the function call "config_item_put"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 17 Nov 2014 19:37:03 +0100

The config_item_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.
