ACPI: Rename OSC_QUERY_TYPE to OSC_QUERY_DWORD
OSC_QUERY_TYPE isn't a "type"; it's an index into the _OSC Capabilities Buffer of DWORDs. Rename OSC_QUERY_TYPE, OSC_SUPPORT_TYPE, and OSC_CONTROL_TYPE to OSC_QUERY_DWORD, etc., to make this clear. No functional change. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
