Hi,


1. You've exported "update_devfreq()" in 1/2 and didn't use it anywhere.
2. If you've added "update_devfreq()" to notify devfreq driver when a new
 max/min is defined, you'll need to add it at set_state, OR
   You may do it with opp_enable()/opp_disable() function and let opp
 notifiers do the homework for you. (no need to update_devfreq().

Cheers,
MyungJoo
