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. Snyder <iws@ovro.caltech.edu> Signed-off-by: Jean Delvare <khali@linux-fr.org>
