[PATCH 1/1] SCSI: Deletion of unnecessary checks before the function call "put_device"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 20 Nov 2014 18:48:52 +0100

The put_device() 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.
