Clean up the link DMA for playback during stop for IPC4 is required to
reset the DMA read/write pointers when the stream is prepared and
restarted after a call to snd_pcm_drain()/snd_pcm_drop(). 

The change is mainly on ASoC. We may go via ASoC tree with Vinod's
Acked-by tag

Ranjani Sridharan (4):
  ASoC: SOF: ipc4-topology: Do not set ALH node_id for aggregated DAIs
  ASoC: SOF: Intel: hda: Handle prepare without close for non-HDA DAI's
  soundwire: intel_ace2x: Send PDI stream number during prepare
  ASoC: SOF: Intel: hda: Always clean up link DMA during stop

Mark,

This is a bug fix. Link: https://github.com/thesofproject/sof/issues/9502

Can you pick it for kernel 6.12? Also

All: Cc: stable@vger.kernel.org # 6.10.x 6.11.x

Thanks,
Bard
