From e32ad07cea1f198db1cc6c2055dd8471b562a535 Mon Sep 17 00:00:00 2001 From: Kalle Komierowski Date: Thu, 2 Feb 2012 16:05:46 +0100 Subject: ab8500_fg: Don't clear the CCMuxOffset bit The CCMuxOffset bit is not kept set. This will force the columb counter of the AB8500 to use the measure offset calibration. This should increase the accuracy of the fuel gauge.
