Subject: [PATCH 3/5] dmaengine: mv_xor_v2: convert callback to helper function
Date:   Tue, 17 Jul 2018 13:30:01 +0300

From: Hanna Hawa <hannah@marvell.com>

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.
