ASoC: SOF: intel: hda: Clean up link DMA for IPC3 during stop
Browse files Browse the repository at this point in the history
commit 90219f1 upstream.

With IPC3, we reset hw_params during the stop trigger, so we should also
clean up the link DMA during the stop trigger.

Fixes: 1bf83fa ("ASoC: SOF: Intel: hda-dai: Do not perform DMA cleanup during stop")
Closes: thesofproject/linux#4455
