Pull ACPI fixes from Rafael Wysocki:
 "These add some new quirks, fix PPTT handling, fix an ACPI utility and
  correct a mistake in the ACPI documentation.

  Specifics:

   - Fix ACPI PPTT handling to avoid sleep in the atomic context when it
     is not present (Sudeep Holla)

   - Add 'backlight=native' DMI quirk for Dell Vostro 15 3535 to the
     ACPI video driver (Chia-Lin Kao)

   - Add ACPI quirks for I2C device enumeration on Lenovo Yoga Book X90
     and Acer Iconia One 7 B1-750 (Hans de Goede)

   - Fix handling of invalid command line option values in the ACPI
     pfrut utility (Chen Yu)

   - Fix references to I2C device data type in the ACPI documentation
     for device enumeration (Andy Shevchenko)"
