Merge tag 'thermal-6.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control fixes from Rafael Wysocki:
 "These remove two recently added excessive lockdep assertions from the
  sysfs-related thermal code and fix two issues in Intel thermal
  drivers.

  Specifics:

   - Drop two lockdep assertions producing false positive warnings from
     the sysfs-related thermal core code (Rafael Wysocki)

   - Fix handling of two recently added module parameters in the Intel
     powerclamp thermal driver (David Arcari)

   - Fix one more deadlock in the int340x thermal driver (Srinivas
     Pandruvada)"

  thermal: intel: powerclamp: Fix cpumask and max_idle module parameters
  thermal: intel: int340x: processor_thermal: Fix additional deadlock
