From 7b83fd9d91a411158f72d36958103c708c3b5a86 Mon Sep 17 00:00:00 2001 From: Aaron Lu Date: Tue, 25 Mar 2014 10:40:09 +0800 Subject: Thermal: move the KELVIN_TO_MILLICELSIUS macro to thermal.h This macro can be used by other component so move it to a common header, but in a slightly different way: define two macros, one macro with an offset and the other doesn't.
