I think you were waiting for me to remove the need for the
comment:

+	/*
+	 * dma_params must be first because rtd->dai->cpu_dai->private_data
+	 * is cast to a pointer of an array of struct davinci_pcm_dma_params in
+	 * davinci_pcm_open.
+	 */

Which is doable.

Do you still want this fixed?

Thanks
