| |
This removes the kelvin to/from Celsius conversion helpers in <linux/thermal.h> which were switched to <linux/temperature.h> helpers.
DECI_KELVIN_TO_MILLICELSIUS_WITH_OFFSET() is only used by ACPI thermal zone driver and the usage is specific to the driver. So this macro is moved to the ACPI thermal driver rather than generic header.
