This patch modifies the device name as devfreq[X] for sysfs by using the 'devfreq' prefix word instead of separate device name. On user-space aspect, user would find the some devfreq drvier with 'devfreq[X]' pattern. So, this patch modify the device name as following: - /sys/class/devfreq/[non-standard device name] -> /sys/class/devfreq/devfreq[X]
