From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Avoiding unused variable warnings when using this macro adds complexity that in simple cases like this one is not justified for the small saving in data. Switch include from acpi.h to mod_devicetable.h which includes the definition of struct acpi_device_id.
