Merge branch 'acpi-scan' 

* acpi-scan: (30 commits)
  ACPI / scan: Fix acpi_bus_get_device() check in acpi_match_device()
  ACPI / scan: Make namespace scanning and trimming mutually exclusive
  ACPI / scan: Make it clear that acpi_bus_trim() cannot fail
  ACPI / scan: Drop acpi_bus_add() and use acpi_bus_scan() instead
  ACPI: update ej_event interface to take acpi_device
  ACPI / scan: Add second pass to acpi_bus_trim()
  ACPI / scan: Change the implementation of acpi_bus_trim()
  ACPI / scan: Drop the second argument of acpi_bus_trim()
  ACPI / scan: Drop the second argument of acpi_device_unregister()
  ACPI: Remove the ops field from struct acpi_device
  ACPI: remove unused acpi_op_bind and acpi_op_unbind
  ACPI / scan: Fix check of device_attach() return value.
  ACPI / scan: Treat power resources in a special way
  ACPI: Remove unused struct acpi_pci_root.id member
  ACPI: Drop ACPI device .bind() and .unbind() callbacks
  ACPI / PCI: Move the _PRT setup and cleanup code to pci-acpi.c
  ACPI / PCI: Rework the setup and cleanup of device wakeup
  ACPI: Add .setup() and .cleanup() callbacks to struct acpi_bus_type
  ACPI: Make acpi_bus_scan() and acpi_bus_add() take only one argument
  ACPI: Replace ACPI device add_type field with a match_driver flag
