[PATCH V3 06/11] power: charger-manager: Concentrate scattered power_supply_changed() calls.

From: Jonghwa Lee
Date: Fri Dec 19 2014 - 03:59:10 EST


Current charger-manager calls power_suuply_changed() whenever charging
status is changed. This patch removes seperated power_supply_changed()
use and let it be called at end of try_charger_enable() function which
is called to set charging/discharging.
