Merge branch 'acpi-fixes' 

* acpi-fixes:
  ACPI / PM: Do not execute _PS0 for devices without _PSC during initialization
  ACPI / scan: do not match drivers against objects having scan handlers
  ACPI / APEI: fix error return code in ghes_probe()
  ACPI / video: ignore BIOS initial backlight value for HP Pavilion g6
  ACPI / video: ignore BIOS initial backlight value for HP m4
  x86 / platform / hp_wmi: Fix bluetooth_rfkill misuse in hp_wmi_rfkill_setup()
