Why did you include? The rest of this patch series starts using it. I decided to include <linux/temperature.h> from <linux/thermal.h> because the existing <linux/thermal.h> provides the conversion helpers. However, not all of the thermal drivers require these conversion helpers, so we can change to include <linux/temperature.h> from each thermal driver instead of including it from <linux/thermal.h>. Which way do you prefer?
