Patch series "add header file for kelvin to/from Celsius conversion
helpers", v4.
There are several helper macros to convert kelvin to/from Celsius in
<linux/thermal.h> for thermal drivers. These are useful for any other
drivers or subsystems, but it's odd to include <linux/thermal.h> just
for the helpers.
This adds a new <linux/units.h> that provides the equivalent inline
functions for any drivers or subsystems, and switches all the users of
conversion helpers in <linux/thermal.h> to use <linux/units.h> helpers.
