Subject: [GIT PULL] ACPI fixes for v5.16-rc3

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-5.16-rc3

with top-most commit 2e13e5aeda156f747919c7111723b9302836fb38

 Merge branch 'acpi-properties'

on top of commit 136057256686de39cc3a07c2e39ef6bc43003ff6

 Linux 5.16-rc2

to receive ACPI fixes for 5.16-rc3.

These fix a NULL pointer dereference in the CPPC library code and
a locking issue related to printing the names of ACPI device nodes
in the device properties framework.

Specifics:

 - Fix NULL pointer dereference in the CPPC library code occurring
   on hybrid systems without CPPC support (Rafael Wysocki).

 - Avoid attempts to acquire a semaphore with interrupts off when
   printing the names of ACPI device nodes and clean up code on
   top of that fix (Sakari Ailus).

Thanks!
