[Rafael J. Wysocki]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-7.1-rc4

with top-most commit af149b667b9472bf981591a6d27efdecd331005a

 Merge branch 'acpi-cppc'

on top of commit 5d6919055dec134de3c40167a490f33c74c12581

 Linux 7.1-rc3

to receive ACPI support fixes for 7.1-rc4.

These fix several platform drivers that use the ACPI companion of the
given platform device without checking its presence, which may lead
to a NULL pointer dereference or other kind of malfunction if the
driver is forced to match a device without an ACPI companion via
driver override, and restore debug log level for some messages in
the ACPI CPPC library:

 - Check ACPI_COMPANION() against NULL during probe in several core
   ACPI device drivers (Rafael Wysocki)

 - Restore log level of messages in amd_set_max_freq_ratio() (Mario
   Limonciello)

Thanks!
