 "These fix two regressions introduced recently, one by reverting the
  problematic commit and one by fixing up locking in the ACPICA core.

  Specifics:

   - Revert a recent change that added an ACPI video blacklist entry for
     HP Pavilion dv6 as it turned to introduce backlight handling
     regressions on some systems (Hans de Goede).

   - Fix locking in the ACPICA core to avoid deadlocks related to table
     loading that were exposed by a recent change in that area (Lv
     Zheng)"

  Revert "ACPI / video: Add force_native quirk for HP Pavilion dv6"
