Subject: [PATCH v2 0/8] add header file for kelvin to/from Celsius conversion helpers

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/temperature.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/temperature.h>
helpers.

* v2
- add deci_kelvin_to_millicelsius_with_offset() in linux/temperature.h
- stop including linux/temperature.h from linux/thermal.h
- include <linux/temperature.h> explicitly from thermal drivers
- fix s/temprature/temperature/ typo in commit log
- use deci_kelvin_to_millicelsius_with_offset() in ACPI thermal zone driver
- don't mix up another fix (format string for cellsius value)
- add Acked-by and Reviewed-by tags

Akinobu Mita (8):
  add header file for kelvin to/from Celsius conversion helpers
  ACPI: thermal: switch to use <linux/temperature.h> helpers
  platform/x86: asus-wmi: switch to use <linux/temperature.h> helpers
  platform/x86: intel_menlow: switch to use <linux/temperature.h>
    helpers
  thermal: int340x: switch to use <linux/temperature.h> helpers
  thermal: intel_pch: switch to use <linux/temperature.h> helpers
  nvme: hwmon: switch to use <linux/temperature.h> helpers
  thermal: remove kelvin to/from Celsius conversion helpers from
    <linux/thermal.h>
