[PATCH 1/1] x86: AMD-perf_event: Deletion of unnecessary checks before the function call "free_percpu"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 22 Nov 2014 14:01:27 +0100

The free_percpu() 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.
