Yes sure, thanks for your quick feedback. I'll propose an updated
version with:
- Empty pdata structures for all the compatibles (only one will remain
  at the end) in order to avoid the "if (pdata)" checks.
- Save the pdata pointer once for all and use derive it directly
  everywhere else.

BTW, you may probably send your Reviewed-by to the DMA series which was
sent a couple of weeks back if you don't have more comments on it?

Thanks,
Miquèl
