Nouveau - Jul 2016 - [PATCH] GPU-DRM-nouveau: Delete an unnecessary check before the function call "pci_dev_put"

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Wed, 20 Jul 2016 19:43:27 +0200

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.
