[PATCH 1/4] acerhdf: Adding support for "manual mode"
From: Peter Feuerer
Date: Sat Apr 26 2014 - 21:31:35 EST
From: Peter Feuerer <peter@xxxxxxxx>
Some Acer models require an additional command to turn off the fan after
bios mode has been enabled. Adding new section in bios table to allow
support for those models, by writing an extra "manual mode" register.
