[PATCH] x86: Intel-perf_event: Delete an unnecessary check before the function call "pci_dev_put"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 3 Feb 2015 12:40:54 +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.
