commit 90219f1bd273055f1dc1d7bdc0965755b992c045 upstream.

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

Cc: stable@vger.kernel.org # 6.4.x Fixes: 1bf83fa6654c ("ASoC: SOF: Intel: hda-dai: Do not perform DMA cleanup during stop") Closes: https://github.com/thesofproject/linux/issues/4455 Closes: https://github.com/thesofproject/linux/issues/4482 Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217673 Signed-off-by: Ranjani Sridharan ranjani.sridharan@linux.intel.com Reviewed-by: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com Reviewed-by: Rander Wang rander.wang@intel.com Reviewed-by: Péter Ujfalusi peter.ujfalusi@linux.intel.com Reviewed-by: Guennadi Liakhovetski guennadi.liakhovetski@linux.intel.com Reviewed-by: Bard Liao yung-chuan.liao@linux.intel.com Signed-off-by: Peter Ujfalusi peter.ujfalusi@linux.intel.com Link: https://lore.kernel.org/r/20230808110627.32375-1-peter.ujfalusi@linux.intel....

Note that many recent Intel based laptops are affected.

Added missing code for 6.4 kernels to keep the fix simple not depending on the other changes. This commit is present in 6.5 tree already.
