    Pull ACPI updates from Rafael Wysocki:
     "These update the ACPICA code in the kernel to upstream revision
      20200430, fix several reference counting errors related to ACPI
      tables, add _Exx / _Lxx support to the GED driver, add a new
      acpi_evaluate_reg() helper, add new DPTF battery participant driver
      and extend the DPFT power participant driver, improve the handling of
      memory failures in the APEI code, add a blacklist entry to the
      backlight driver, update the PMIC driver and the processor idle
      driver, fix two kobject reference count leaks, and make a few janitory
      changes.
    
      Specifics:
    
       - Update the ACPICA code in the kernel to upstream revision 20200430:
    
          - Move acpi_gbl_next_cmd_num definition (Erik Kaneda).
    
          - Ignore AE_ALREADY_EXISTS status in the disassembler when parsing
            create operators (Erik Kaneda).
    
          - Add status checks to the dispatcher (Erik Kaneda).
    
          - Fix required parameters for _NIG and _NIH (Erik Kaneda).
    
          - Make acpi_protocol_lengths static (Yue Haibing).
    
       - Fix ACPI table reference counting errors in several places, mostly
         in error code paths (Hanjun Guo).
    
       - Extend the Generic Event Device (GED) driver to support _Exx and
         _Lxx handler methods (Ard Biesheuvel).
    
       - Add new acpi_evaluate_reg() helper and modify the ACPI PCI hotplug
         code to use it (Hans de Goede).
    
       - Add new DPTF battery participant driver and make the DPFT power
         participant driver create more sysfs device attributes (Srinivas
         Pandruvada).
    
       - Improve the handling of memory failures in APEI (James Morse).
    
       - Add new blacklist entry for Acer TravelMate 5735Z to the backlight
         driver (Paul Menzel).
    
       - Add i2c address for thermal control to the PMIC driver (Mauro
         Carvalho Chehab).
    
       - Allow the ACPI processor idle driver to work on platforms with only
         one ACPI C-state present (Zhang Rui).
    
       - Fix kobject reference count leaks in error code paths in two places
         (Qiushi Wu).
    
       - Delete unused proc filename macros and make some symbols static
         (Pascal Terjan, Zheng Zengkai, Zou Wei)"
