Subject: dmaengine: fsldma: convert callback to helper function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=af1a5a5114e0f3646dbe1be0d42ec1a3a373223f;p=linux-beck.git

dmaengine: fsldma: 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.
