[PATCH 2/6] PM / devfreq: Modify the device name as devfreq[X] for sysfs

Show all headers | View raw

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]
