Merge branch 'acpi-driver'

Merge changes related to ACPI support in device drivers for 7.4:

 - Switch over the users of acpi_get_first_physical_node(), that
   was inherently racy and therefore not really safe to use, to use
   its replacement acpi_bus_get_primary_device(), and eliminate the
   former (Rafael Wysocki)

 - Add !CONFIG_ACPI stubs for acpi_find_child_device() and
   acpi_device_uid() (Mario Limonciello and Robin Murphy)

* acpi-driver:
  ACPI: bus: Drop acpi_get_first_physical_node()
  efi/dev-path-parser: Switch to use acpi_bus_get_primary_device()
  ALSA: hda: tas2781: Switch to use acpi_bus_get_primary_device()
  ALSA: hda: cs35l41: Switch to use acpi_bus_get_primary_device()
  iommu/arm-smmu-v3: Switch to use acpi_bus_get_primary_device()
  ACPI: Add stub for acpi_find_child_device()
  ACPI: bus: Provide !ACPI stub for acpi_device_uid()
  ALSA: hda: aw88399: Switch to use acpi_bus_get_primary_device()
  ASoC: loongson: Switch to use acpi_bus_get_primary_device()
  ASoC: intel: boards: Switch to use acpi_bus_get_primary_device()
  ASoC: amd: acp3x-es83xx: Switch to use acpi_bus_get_primary_device()
  ASoC: amd: acp-es8336: Switch to use acpi_bus_get_primary_device()
  thunderbolt: Switch to use acpi_bus_get_primary_device()
  platform/x86: apple-gmux: Switch to use acpi_bus_get_primary_device()
  platform/x86: x86-android-tablets: Use acpi_bus_get_primary_device()
  platform/x86: serdev_helpers: Switch to use acpi_bus_get_primary_device()
  platform/x86: yogabook: Switch to use acpi_bus_get_primary_device()
  ACPI: amba: Switch to use acpi_bus_get_primary_device()
  ACPI: bus: Use acpi/acpi_bus.h without CONFIG_ACPI
