Current rsnd sets dma_slave_config :: slave_id field for DMAEngine,
but it is no longer needed. Let's remove it.

i noticed this patch was dropped in v5, and thus not applied by Vinod?
Did I miss a discussion about that?

Thank you for pointing it, and sorry I didn't explain about this patch.
Yes, I dropped this patch, because, Renesas sound card can't use
Audio DMA peri peri via DMAEngine anymore.
Sound card is now customized not to use DMAEngine.
Above change (= remove slave_id from sound driver) is done in sound driver
side customize patch-set.
Otherwise, we will have conflict between DMAEngine <-> Sound branch
Best regards
