Subject: [PATCH] hwmon: (asus_atk0110) Add quirk for Asus M5A78L
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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.
