Merge tag 'acpi-5.20-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more ACPI updates from Rafael Wysocki:
 "These fix up direct references to the fwnode field in struct device
  and extend ACPI device properties support.

  Specifics:

   - Replace direct references to the fwnode field in struct device with
     dev_fwnode() and device_match_fwnode() (Andy Shevchenko)

   - Make the ACPI code handling device properties support properties
     with buffer values (Sakari Ailus)"
