PM / devfreq: Simplify the sysfs name of devfreq-event device
This patch just removes '.' character from the sysfs name of devfreq-event device as following. Usually, the subsystem uses the similiar naming style such as {framework name}{Number}. - old : /sys/class/devfreq-event/event.(X) - new : /sys/class/devfreq-event/event(X) And this patch initializes the value of 'event_no' with -1 in order to remove the unneeded operation (-1) when calling the atomic_inc_return(&event_no). Lastly, this patch adds the ABI document for devfreq-event class. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com>
