6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rafael J. Wysocki rafael.j.wysocki@intel.com
[ Upstream commit 1c426fd09ca85fb77f120f7933e39eb9df99a39a ]
Use DEFINE_FREE() to define a __free function for dropping thermal zone template reference counters and use it along with __free() to simplify code in some places.
No intentional functional impact.
