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

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 30 Nov 2014 10:59:10 +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.
