Linus Torvalds 48f76a1271 Merge tag 'acpi-7.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm ...

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)"
