Merge tag 'acpi-4.19-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to the most recent upstream
  revision (which includes a regression fix and other improvements),
  make ACPICA clear the status of all ACPI events when entering sleep
  states (to restore the previous behavior) and update the ACPI
  operation region driver for the CrystalCove PMIC.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20180810
     including:
      * Fix for AML parser regression causing it to mishandle opcodes
        that open a scope upon parse failures (Erik Schmauss)
      * Fix for a reference counting issue on large systems (Erik
        Schmauss)
      * Fix to discard values coming from register reads that have
        failed (Erik Schmauss)
      * Two acpiexec fixes (Bob Moore, Erik Schmauss)
      * Debugger cleanup (Bob Moore)
      * Cleanup of duplicate table error message (Bob Moore)
      * Cleanup of hex detection in the utilities (Erik Schmauss)

   - Make ACPICA clear the status of all ACPI events when entering sleep
     states again to avoid functional regressions (Rafael Wysocki)

   - Update the ACPI operation region driver for the CrystalCove PMIC to
     cover all of the known operation region fields (Hans de Goede)"
