All devices do this - it's done as part of the driver model core code so there is no need for individual buses to do anything.
How should one realize that this does not apply to the original file under discussion, sound/soc/codecs/sgtl5000.c? The associated structure is snd_soc_codec_driver. What code could one look for at the call sites of the probe and remove functions to know that managed memory can be used?
That's not a device model driver; the way you should realise this is that there's no device being registered on a bus which is matched by the driver core.
