Merge branches 'acpica' and 'acpi-bus'

Merge an ACPICA fix and a core ACPI support code fix for 7.0-rc5:

 - Update the format of the last argument of _DSM to avoid printing
   confusing error messages in some cases (Saket Dumbre)

 - Fix MFD child automatic modprobe issue by removing a stale check
   from acpi_companion_match() (Pratap Nirujogi)

* acpica:
  ACPICA: Update the format of Arg3 of _DSM

* acpi-bus:
  ACPI: bus: Fix MFD child automatic modprobe issue
