I just had a look at the documentation concerning this topic: 

Documentation/thermal/sysfs-api.txt:162

temp           Current temperature as reported by thermal zone (sensor)
            Unit: millidegree Celsius
            RO
            Required


It is expected to be in millidegree, so I think we should discuss, modify 
and apply the patch.
