Merge tag 'thermal-6.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control fixes from Rafael Wysocki:
 "Fix two issues introduced recently and one driver problem leading to a
  NULL pointer dereference in some cases.

  Specifics:

   - Add missing EXPORT_SYMBOL_GPL in the thermal core and add back the
     required 'trips' property to the thermal zone DT bindings (Daniel
     Lezcano)

   - Prevent the int340x_thermal driver from crashing when a package
     with a buffer of 0 length is returned by an ACPI control method
     evaluated by it (Lee, Chun-Yi)"

* tag 'thermal-6.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR
  dt-bindings: thermal: Fix missing required property
  thermal/core: Add missing EXPORT_SYMBOL_GPL
