While the HDAudio codec driver expectations must be met - store valid pointer to HDAudio LINK stream in substream->runtime->private_data - the code is more readable and easier to maintain if dma_data stores pointers to both HOST and LINK stream. DAI BE operations can refer to the LINK stream with data->link_stream, similarly to how DAI FE operations access the HOST stream with data->host_stream.
