1694 ``dma_addr``, ``dma_bytes`` and ``dma_private``. ``dma_area``1699 buffer in bytes. ``dma_private`` is used for the ALSA DMA allocator.1709 necessary. ``dma_addr`` is also optional. You can use dma_private as3564 ``substream->dma_private`` in turn. You can cast the pointer like::3566 struct snd_sg_buf *sgbuf = (struct snd_sg_buf *)substream->dma_private;
