455Another example to override the codec vendor id from 0x12345678 to
4560xdeadbeef is like below:

465In the similar way, you can override the codec subsystem_id via
466`[subsystem_id]`, the revision id via `[revision_id]` line.
467Also, the codec chip name can be rewritten via `[chip_name]` line.
