      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)"

      provide arch_test_bit_acquire for architectures that define test_bit · d6ffe606
      Mikulas Patocka authored
      Some architectures define their own arch_test_bit and they also need
      arch_test_bit_acquire, otherwise they won't compile.  We also clean up
      the code by using the generic test_bit if that is equivalent to the
      arch-specific version.
