Merge tag 'acpi-4.13-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull ACPI fixes from Rafael Wysocki:
 "These fix two issues in the ACPI SoC drivers (Intel LPSS and AMD APD),
  a crash in the PCC mailbox initialization code and a WDAT watchdog
  initialization failure.

  Specifics:

   - Fix a device ID of Hisilicon Hip07/08 in the ACPI APD (AMD SoC)
     driver (Hanjun Guo).

   - Fix list corruption (introduced during the 4.11 cycle) in the ACPI
     LPSS (Intel SoC) driver (Hans de Goede).

   - Fix PCC mailbox handling code crash during initialization when PCCT
     is not present and PCC channel 0 is requested (Hoan Tran).

   - Fix a WDAT watchdog initialization issue causing platform device
     creation to fail due to partially overlapping address ranges in
     resources (Ryan Kennedy)"
