[PATCH v4 34/41] dmaengine: xgene-dma: convert callback to helper function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is in preperation of moving to a callback that provides results to the
callback for the transaction. The conversion will maintain current behavior
and the driver must convert to new callback mechanism at a later time in
order to receive results.
