ASoC: SOF: ipc4-topology: Only handle dai_config with HW_PARAMS for ChainDMA
The DMA Link ID is only valid in snd_sof_dai_config_data when the dai_config is called with HW_PARAMS. The commit that this patch fixes is actually moved a code section without changing it, the same bug exists in the original code, needing different patch to kernel prior to 6.9 kernels. Cc: stable@vger.kernel.org Fixes: 3858464 ("ASoC: SOF: ipc4-topology: change chain_dma handling in dai_config") Link: #5116 Signed-off-by: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>
