[PATCH 21/40] ab8500-btemp: Defer btemp filtering while initialising

From: Lee Jones
Date: Fri Feb 15 2013 - 07:52:31 EST


From: Rupesh Kumar <rupesh.kumar@xxxxxxxxxxxxxx>

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.
