[alsa-devel] [PATCH 1/1] ALSA: powermac: Deletion of an unnecessary check before the function call "pci_dev_put"

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Mon, 17 Nov 2014 13:35:54 +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.
