Merge tag 'acpi-4.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These fix a system resume regression from the 4.13 cycle, clean up
device table handling in the ACPI core, update sysfs ABI documentation
of a couple of drivers and add an expected switch fall-through marker
to the SPCR table parsing code.
Specifics:
- Revert a problematic EC driver change from the 4.13 cycle that
introduced a system resume regression on Thinkpad X240 (Rafael
Wysocki).
- Clean up device tables handling in the ACPI core and the related
part of the device properties framework (Andy Shevchenko).
- Update the sysfs ABI documentatio of the dock and the INT3407
special device drivers (Aishwarya Pant).
- Add an expected switch fall-through marker to the SPCR table
parsing code (Gustavo Silva)"
