Hi Andi,

Quoting Andi Shyti <andi.shyti@xxxxxxxxxxx>:

Hi Gustavo,

desc = dmaengine_prep_slave_sg(dma->ch, sgt->sgl, sgt->nents,
dma->direction, DMA_PREP_INTERRUPT);

+ if (!desc) {
+ dev_err(&sdd->master->dev,
+ "%s:dmaengine_prep_slave_sg Failed\n", __func__);
+ return;
+ }
+

I'm sorry, I would nack this patch for now. There was a smilar I
sent before, but, as Krzysztof said, this needs more testing and
a proper solution.


Yeah, I get it.

That's anyway in my todo list.


That's great.

Thanks,
Andi

Thanks!
