[RESEND][PATCH 1/5] Update drivers names to the ones invoked by i2c-powermac

From: Goffredo Baroncelli
Date: Tue Nov 11 2014 - 08:25:27 EST


Update drivers names to the ones invoked by i2c-powermac:
- therm_ds1775 -> MAC,ds1775
- therm_adm1030 -> MAC,adm1030
The background fan control loop is started from
the devices probing methods.
