Check the return value please, this can fail.
+static int skl_get_format(struct snd_pcm_substream *substream,

Should be no need to cast away from void.
- if (substream->runtime->dma_area)
memset(substream->runtime->dma_area, 0,params_buffer_bytes(params));
Why do we need to memset here?
- dma_params = (struct skl_dma_params *)
snd_soc_dai_get_dma_data(dai, substream);- pm_runtime_mark_last_busy(dai->dev);
- pm_runtime_put_autosuspend(dai->dev);
- kfree(dma_params);
We check elsewhere for dma_params being NULL, shouldn't we set it to be NULL when we free?
