Merge branch 'acpi-driver'

Merge updates of core ACPI device drivers for 7.2-rc1:

 - Fix multiple issues related to probe, removal and missing NVDIMM
   device notifications in the ACPI NFIT driver (Rafael Wysocki)

 - Add support for devres-based management of ACPI notify handlers to
   the ACPI core (Rafael Wysocki)

 - Switch multiple core ACPI device drivers (including the ACPI PAD,
   ACPI video bus, ACPI HED, ACPI thermal zone, ACPI AC, ACPI battery,
   and ACPI NFIT drivers) over to using devres-based resource management
   during probe (Rafael Wysocki)

 - Replace mutex_lock/unlock() with guard()/scoped_guard() in the ACPI
   PMIC driver (Maxwell Doose)

 - Fix message kref handling in the dead device path of the ACPI IPMI
   address space handler (Yuho Choi)

 - Use sysfs_emit() in idlecpus_show() in the ACPI processor aggregator
   device (PAD) driver (Yury Norov)

 - Clean up device_id_scheme initialization in the ACPI video bus driver
   (Jean-Ralph Aviles)
