| |
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).
