device_get_match_data() in ACPI case calls similar to acpi_match_device(). Hence there is no need to duplicate the call. Just assign what is in the id->driver_data.

Would it not be simpler to just:

/* acpi_driver definition */ --- We don't use the desc in sof_broadwell_probe(), so we can just pass the id->driver_data
