Hi Victor,

This gets the standard question for a temperature sensor...
Why IIO and not hwmon?  Good to have that info in the cover letter or
patch description.

I'd normally moan about the wild cards even though they are only
in patch titles, but meh, the datasheet uses the wild card
so we are probably safe for a while at least!
