Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6: (32 commits)
  ACPI: i2c-scmi: don't use acpi_device_uid()
  ACPI: simplify building device HID/CID list
  ACPI: remove acpi_device_uid() and related stuff
  ACPI: remove acpi_device.flags.hardware_id
  ACPI: remove acpi_device.flags.compatible_ids
  ACPI: maintain a single list of _HID and _CID IDs
  ACPI: make sure every acpi_device has an ID
  ACPI: use acpi_device_hid() when possible
  ACPI: fix synthetic HID for \_SB_
  ACPI: handle re-enumeration, when acpi_devices might already exist
  ACPI: factor out device type and status checking
  ACPI: add acpi_bus_get_status_handle()
  ACPI: use acpi_walk_namespace() to enumerate devices
  ACPI: identify device tree root by null parent pointer, not ACPI_BUS_TYPE
  ACPI: enumerate namespace before adding functional fixed hardware devices
  ACPI: convert acpi_bus_scan() to operate on an acpi_handle
  ACPI: add acpi_bus_get_parent() and remove "parent" arguments
  ACPI: remove unnecessary argument checking
  ACPI: remove redundant "type" arguments
  ACPI: remove acpi_device_set_context() "type" argument
