Now that this patch is already applied my remarks can only be addressed
in a follow up patch. (Perhaps such a patch is already queued.)

The code in atmel-pcm-pdc.c and atmel-pcm-dma.c will now either be part
of the snd-soc-atmel_ssc_dai.ko or be built-in. That means, I think,
that:
- the (in total) four uses of EXPORT_SYMBOL() in these two files can be
  dropped;
- MODULE_AUTHOR() and friends, and probably also the include of
  linux/module.h, can be dropped from these two files.

Furthermore, the references to CONFIG_SND_ATMEL_SOC_PDC_MODULE and
CONFIG_SND_ATMEL_SOC_DMA_MODULE in atmel-pcm.h can be removed now.

Thanks,

Paul Bolle
