Subject: dmaengine: fsl_raid: convert callback to helper function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1595c3e1bf4dc7d75d8623795040fc71d340ebe3;p=linux-beck.git

dmaengine: fsl_raid: 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.
