[PATCH] platform/x86: asus-wmi: fix cpufv sysfs file permission
From: JÃrÃmy Lefaure
Date: Fri Apr 21 2017 - 22:24:17 EST
The cpufv sysfs file is defined as readable by anyone even if the
attribute does not have a show function. The result of every read is an
IO error. This file should be write only.
