Merge tag 'thermal-6.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control fixes from Rafael Wysocki:
 "These fix a thermal core breakage introduced by one of the recent
  changes, amend those changes by adding 'const' to a new callback
  argument and fix two memory leaks.

  Specifics:

   - Unbreak disabled trip point check in handle_thermal_trip() that may
     cause it to skip enabled trip points (Rafael Wysocki)

   - Add missing of_node_put() to of_find_trip_id() and
     thermal_of_for_each_cooling_maps() that each break out of a
     for_each_child_of_node() loop without dropping the reference to the
     child object (Julia Lawall)

   - Constify the recently added trip argument of the .get_trend()
     thermal zone callback (Rafael Wysocki)"
