Subject: [PATCH 2/2] cpufreq: powernow-k8: Delete an unnecessary return
 statement in two functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 15 Feb 2018 20:14:32 +0100

The script "checkpatch.pl" pointed information out like the following.

WARNING: void function return statements are not generally useful

Thus remove such a statement in the affected functions.
