This call is defined in imx-pcm.h as:
#if IS_ENABLED(CONFIG_SND_SOC_IMX_PCM_DMA)
int imx_pcm_dma_init(struct platform_device *pdev);
#else
static inline int imx_pcm_dma_init(struct platform_device *pdev)
{
  return -ENODEV;
}
#endif

So, I don't understand why this error happen, as well as I can not
reproduce this...
