Functions
static void	audio_stream_sync_to_hw (struct audio_stream *stream, const struct dma_status *dma_status)
	Replicates the hardware state of the DMA buffer as a struct audio_stream.

Detailed Description

Synchronisation of an audio stream with the state of its DMA buffer.

Kept separate from sof/audio/audio_stream.h because it needs the Zephyr DMA driver definitions, which most users of the audio stream API do not. Only available in Zephyr builds.
