From 0024b2ac374490de46bfd35c43002c7800ad14ed Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Wed, 20 Jul 2016 13:12:24 -0700 Subject: [PATCH] dmaengine: nbpfaxi: convert callback to helper function 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.
