Subject: dmaengine: mv_xor: convert callback to helper function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ee7681a48063111c5bcb0385809ec2be90eabd70;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dmaengine: mv_xor: 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.
