Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-7.0-rc5

with top-most commit 5cbcd6c0742a2986782a9e2c92aa250d8f5c137d

Merge branches 'acpica' and 'acpi-bus'

on top of commit f338e77383789c0cae23ca3d48adcc5e9e137e3c

Linux 7.0-rc4

to receive ACPI support fixes for 7.0-rc5.

These fix an MFD child automatic modprobe issue introduced recently,
an ACPI processor driver issue introduced by a previous fix and an
ACPICA issue causing confusing messages regarding _DSM arguments to
be printed:

- Update the format of the last argument of _DSM to avoid printing
confusing error messages in some cases (Saket Dumbre)

- Fix MFD child automatic modprobe issue by removing a stale check
from acpi_companion_match() (Pratap Nirujogi)

- Prevent possible use-after-free in acpi_processor_errata_piix4()
from occurring by rearranging the code to print debug messages
while holding references to relevant device objects (Rafael Wysocki)

Thanks!
