From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Do some assorted cleanups in thermal_zone_trip_update():
* Compute the trend value upfront. * Move old_target definition to the block where it is used. * Adjust white space around diagnositc messages and locking. * Use suitable field formatting in a message to avoid an explicit cast to int.
