From 8705b719573d2159adde10af9c6a4d8806b7d27b Mon Sep 17 00:00:00 2001

Subject: [PATCH 28/30] dell/e6*30: disable the ME device in devicetree
we neuter anyway. disabling it in devicetree will prevent linux
from ever trying to use it or load a driver for it, and thus
might prevent benign error messages from appearing in dmesg.
this change was suggested by nicholas when asked on irc.
