From 58f055e5314856a3badfa61fe144347903488989 Mon Sep 17 00:00:00 2001 From: "Ira W. Snyder" Date: Wed, 23 Sep 2009 22:59:44 +0200 Subject: hwmon: (ltc4245) Clear faults at startup When power is applied to the ltc4245 chip it sometimes reports spurious faults, which are exposed as alarms in the hwmon output. Clear the fault register when the driver is installed to clear the alarms. Signed-off-by: Ira W.
