Subject[PATCH 03/12] PM / devfreq: Move private devfreq_update_stats() into devfreq
Date
From: Chanwoo Choi <cwchoi00@gmail.com>

THe devfreq_update_stats() updates the 'struct devfreq_dev_status'
in order to get current status of devfreq device. It is only used
for the governors.

This patch moves the devfreq_update_stats() into devfreq directory.
