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)"

* tag 'acpi-5.20-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  ACPI: property: Fix error handling in acpi_init_properties()
  ACPI: VIOT: Do not dereference fwnode in struct device
  ACPI: property: Read buffer properties as integers
  ACPI: property: Add support for parsing buffer property UUID
  ACPI: property: Unify integer value reading functions
  ACPI: property: Switch node property referencing from ifs to a switch
  ACPI: property: Move property ref argument parsing into a new function
  ACPI: property: Use acpi_object_type consistently in property ref parsing
  ACPI: property: Tie data nodes to acpi handles
  ACPI: property: Return type of acpi_add_nondev_subnodes() should be bool
