Subject[PATCH 45/57] power: ab8500: defer btemp filtering while init
Date
From: Rupesh Kumar <rupesh.kumar@stericsson.com>

Due to btemp filtering enabled during init, temp values
reported to charge algorithm driver started from 0.
As a result,charge algorithm was going into wrong
state and charging was stopped.
This patch defers btemp filtering till init is done.
