Subject: [ 011/135] hwmon: (asus_atk0110) Add quirk for Asus M5A78L

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

------------------

From: Luca Tettamanti <kronos.it@...il.com>

commit 43ca6cb28c871f2fbad10117b0648e5ae3b0f638 upstream.

The old interface is bugged and reads the wrong sensor when retrieving
the reading for the chassis fan (it reads the CPU sensor); the new
interface works fine.
