[PATCH 42/57] power: charging: Allow capacity to raise from 1%

From: mathieu . poirier
Date: Tue Sep 25 2012 - 12:17:45 EST


From: Hakan Berg <hakan.berg@xxxxxxxxxxxxxx>

When battery capacity was going below 1% fg in not supposed
to report 0% unless we've got the LOW_BAT IRQ, no matter
what the FG-algorithm says. This made fg get stuck at 1% if
charger is connected when capacity is 1%.
That problem is addressed with this patch.
