Merge tag 'acpi-6.1-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI updates from Rafael Wysocki:
"These fix two issues, in APEI and in the int3472 driver, clean up the
ACPI thermal driver, add ACPI support for non-GPE system wakeup events
and make the system reboot code use the S5 (system off) state by
default.
Specifics:
- Fix ACPI device object reference counting in (recently updated)
skl_int3472_fill_clk_pdata() (Andy Shevchenko).
- Fix a memory leak in APEI by avoiding to add a task_work to kernel
threads running when an asynchronous error is detected (Shuai Xue).
- Add ACPI support for handling system wakeups via GPIO wake capable
IRQs in addition to GPEs (Raul E Rangel).
- Make the system reboot code put ACPI-enabled systems into the S5
(system off) state which is necessary for some platforms to work as
expected (Kai-Heng Feng).
- Make the white space usage in the ACPI thermal driver more
consistent and drop redundant code from it (Rafael Wysocki)"
