It has been awhile since this patch was submitted and merged by
Eduardo. I replace him to co-maintain the thermal framework with Rui.

While figuring out the internals for code cleanup, I ended up in this
function above.

Why do you have to use this routine instead of the generic one in
get_tz_trend()?
