From 775fa8c3aa22df720f433e871f94cfb182f5913d Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Tue, 31 Jan 2017 16:47:56 +0900 Subject: 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.
