Subject: [PATCH 2.6.0-test3]bugfix for initialization bug in adm1021 driver

While initializing the adm1021 device, the driver is performing a conversion
from fixed point to Celcius on values that were declaired as Celcius. On
my Dell Precision 220 this results in a shutdown after a couple of minutes
running.

This is a very simple patch against the 2.6.0-test3 tree that just removes the
conversion.

Applied, thanks.

Next time you might want to CC: me to make sure I catch this.
