[PATCH 4/8] platform/x86: intel_menlow: switch to use <linux/temperature.h> helpers

From: Akinobu Mita
Date: Sun Nov 24 2019 - 09:09:32 EST


This switches the intel_menlow driver to use deci_kelvin_to_celsius() and
celsius_to_deci_kelvin() in <linux/temperature.h> instead of helpers in
<linux/thermal.h>.

This is preparation for centralizing the kelvin to/from Celsius conversion
helpers in <linux/temprature.h>.
