Merge tag 'acpi-4.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull ACPI fixes from Rafael Wysocki:
 "These fix the initialization of resources in the ACPI WDAT watchdog
  driver, a recent regression in the ACPI device properties handling, a
  recent change in behavior causing the ACPI_HANDLE() macro to only work
  for GPL code and create a MAINTAINERS entry for ACPI PMIC drivers in
  order to specify the official reviewers for that code.

  Specifics:

   - Fix the initialization of resources in the ACPI WDAT watchdog
     driver that uses unititialized memory which causes compiler
     warnings to be triggered (Arnd Bergmann).

   - Fix a recent regression in the ACPI device properties handling that
     causes some device properties data to be skipped during enumeration
     (Sakari Ailus).

   - Fix a recent change in behavior that caused the ACPI_HANDLE() macro
     to stop working for non-GPL code which is a problem for the NVidia
     binary graphics driver, for example (John Hubbard).

   - Add a MAINTAINERS entry for the ACPI PMIC drivers to specify the
     official reviewers for that code (Rafael Wysocki)"
