Subject: [PATCH 1/1] PCI: hotplug: Deletion of an unnecessary check before
 the function call "pci_dev_put"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 20 Nov 2014 17:42:23 +0100

The pci_dev_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.
