Revision 0b2f18e7aeef86f966bbfccec8d698e05ccc4631 authored by Linus Torvalds on 28 August 2020, 20:17:14 UTC, committed by Linus Torvalds on 28 August 2020, 20:17:14 UTC 
Merge tag 'acpi-5.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
 
Pull ACPI fixes from Rafael Wysocki:
 "These fix two recent issues in the ACPI memory mappings management
  code and tighten up error handling in the ACPI driver for AMD SoCs
  (APD).

  Specifics:

   - Avoid redundant rounding to the page size in acpi_os_map_iomem() to
     address a recently introduced issue with the EFI memory map
     permission check on ARM64 (Ard Biesheuvel).

   - Fix acpi_release_memory() to wait until the memory mappings
     released by it have been really unmapped (Rafael Wysocki).

   - Make the ACPI driver for AMD SoCs (APD) check the return value of
     acpi_dev_get_property() to avoid failures in the cases when the
     device property under inspection is missing (Furquan Shaikh)"
