The asus-wmi driver doesn't implement the thermal device functionality
directly, so including <linux/thermal.h> just for DECI_KELVIN_TO_CELSIUS()
is a bit odd.

This switches the asus-wmi driver to use deci_kelvin_to_millicelsius() in
<linux/units.h>.

Similar comment about ordering. Can we move it to the end after dmi.h?

%d -> %ld must be explained in the commit message (e.g. "due to
function returned type).

I prefer to have this in one line.

It causes line over 80 characters.
We had the same conversation in v1 :)
