From 0fa11dbc234268c4160b81f67220308dea3c156a Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Thu, 22 Nov 2012 16:53:46 +0900 Subject: charger-manager: Fix bug related to checking fully charged state of battery 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.
