3.13-stable review patch. If anyone has any objections, please let me know.

From: Chris Ruehl <chris.ruehl@xxxxxxxxxxxx>
commit e3365d0974ed64157f5b5a576c611057dc40a595 upstream.
The offset for the 2bit register calculate wrong, this patch
fixes the problem. The debugfs printout for oconf, iconfa, iconfb
now shows the real values.
