wmi: convert acpi_evaluate_object() to acpi_execute_simple_method()
acpi_execute_simple_method() is a new ACPI API introduced to invoke an ACPI control method that has single integer parameter and no return value. Convert acpi_evaluate_object() to acpi_execute_simple_method() in drivers/platform/x86/wmi.c Signed-off-by: Zhang Rui <rui.zhang@intel.com> CC: Matthew Garrett <matthew.garrett@nebula.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
