PM / devfreq: Modify the device name as devfreq(X) for sysfs
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) Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com>
