Yes, let's try this way, in the former patch

"ASoC: pxa: remove the dmaengine compat need" :
+++ b/sound/arm/pxa2xx-pcm-lib.c
@@ -126,7 +127,7 @@ int __pxa2xx_pcm_open(struct snd_pcm_substream *substream)
                return ret;
 
        return snd_dmaengine_pcm_open(
-               substream, dma_request_slave_channel(rtd->platform->dev,
+               substream, dma_request_slave_channel(rtd->cpu_dai->dev,
                                                     dma_params->chan_name));
 }

The cpu_dai device should be either pxa27x_ac97 or pxa-ssp-dai.<Id>, and amend
the dma slave map accordingly.

Cheers.
