Subject: dmaengine: xgene-dma: convert callback to helper function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b1f884a5ff23534c3808926aeb62187be55e751e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dmaengine: xgene-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.
