[PATCH v2 1/3] charger-manager: Fix bug related to checking fullycharged state of battery

From: Chanwoo Choi
Date: Thu Nov 22 2012 - 15:04:35 EST


This patch fix bug related to checking fully charged state of battery
when charger-manager call is_full_charged() function. After reading
property of charger/fuel-gauge through power_supply API, val.intval is
more than 1. So, is_full_charged() function always return true. If true,
battery means fully charged state.
