From a1d4eaaf4021a3a0c1299f254faf7b50ca9ddbfa Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Wed, 20 Jul 2016 13:10:42 -0700 Subject: dmaengine: at_xdmac: 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.
