Merge tag 'acpi-5.10-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These fix recent regression in the APEI code and initialization issue
in the ACPI fan driver.
Specifics:
- Make the APEI code avoid attempts to obtain logical addresses for
registers located in the I/O address space to fix initialization
issues (Aili Yao)
- Fix sysfs attribute initialization in the ACPI fan driver (Guenter
Roeck)"
