Merge tag 'thermal-6.9-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control fixes from Rafael Wysocki:
 "These revert a problematic optimization commit and address a devfreq
  cooling device issue.

  Specifics:

   - Revert thermal core optimization that introduced a functional issue
     causing a critical trip point to be crossed in some cases (Daniel
     Lezcano)

   - Add missing conversion between different state ranges to the
     devfreq cooling device driver (Ye Zhang)"

  thermal: devfreq_cooling: Fix perf state when calculate dfc res_util
  Revert "thermal: core: Don't update trip points inside the hysteresis range"
