Subject: [PATCH 1/3] block-cciss: Deletion of an unnecessary check before
 the function call "put_disk"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 18 Jan 2015 11:14:16 +0100

The put_disk() 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.
