Merge tag 'acpi-4.9-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These fix an issue related to system resume in the new WDAT-based
watchdog driver and a return value of a stub function in the ACPI CPPC
framework.
Specifics:
- Update the ACPI WDAT-based watchdog driver to ping the hardware
during system resume to prevent a reset from occurring after the
resume is complete (Mika Westerberg).
- Fix the return value of the pcc_mbox_request_channel() stub for
CONFIG_PCC unset (Hoan Tran)"
