    Pull two ACPI CPPC fixes from Rafael Wysocki:
     "One of them fixes a crash in KVM encountered by Sebastian in
      linux-next and introduced by a recent intel_pstate change that caused
      the driver to use the ACPI CPPC code and uncovered a missing NULL
      pointer check in it.
    
      The other one fixes a possible use-after-free in the same code area.
    
      Summary:
    
       - Fix a crash in KVM encountered in linux-next and introduced by a
         recent intel_pstate change that caused the driver to use the ACPI
         CPPC code and uncovered a missing NULL pointer check in it
         (Sebastian Andrzej Siewior).
    
       - Fix a possible use-after-free in the same code area (Rafael
         Wysocki)"
