Subject: [GIT PULL] ACPI fix for v5.15-rc5

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-5.15-rc5

with top-most commit 3fb937f441c64af1eec60bfd3732f64001fcc534

 PCI: ACPI: Check parent pointer in acpi_pci_find_companion()

on top of commit 9e1ff307c779ce1f0f810c7ecce3d95bbae40896

 Linux 5.15-rc4

to receive an ACPI fix for 5.15-rc5.

This fixes a recent ACPI-related regression in the PCI subsystem
that introduced a NULL pointer dereference possible to trigger
from user space via sysfs on some systems.

Thanks!
