adt7470: make automatic fan control really work
It turns out that the adt7470's automatic fan control algorithm only works when the temperature sensors get updated. This in turn happens only when someone tells the chip to read its temperature sensors. Regrettably, this means that we have to drive the chip periodically. Signed-off-by: Darrick J.
