From b8bdebb98a56c953808388295670f79b88313fd1 Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Wed, 20 Jul 2016 13:13:05 -0700 Subject: [PATCH] dmaengine: sirf-dma: 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.
