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)"
