Merge branches 'acpi-video' and 'acpi-hotplug' 

* acpi-video:
  ACPI: move models with win8 brightness problems from win8 blacklist to use_native_backlight
  ACPI / video: Fix backlight taking 2 steps on a brightness up/down keypress

* acpi-hotplug:
  ACPI / hotplug / PCI: Fix sparse non static symbol warning
  ACPI / hotplug: Simplify acpi_set_hp_context()
  ACPI / hotplug / PCI: Eliminate acpiphp_dev_to_bridge()
