Subject: [PATCH 1/1] net-PA Semi: Deletion of unnecessary checks before the
 function call "pci_dev_put"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 29 Nov 2014 18:55:40 +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.
