Pull ACPI support fixes from Rafael Wysocki:
"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)"
