From: Dave Jiang Date: Wed, 20 Jul 2016 20:10:42 +0000 (-0700) Subject: dmaengine: at_xdmac: convert callback to helper function X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a1d4eaaf4021a3a0c1299f254faf7b50ca9ddbfa;p=linux-beck.git 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.
