#1478722 — [PATCH] dmaengine: dmatest: Apply copy_align to DMA_SG as well

Subject[PATCH] dmaengine: dmatest: Apply copy_align to DMA_SG as well
Message-ID<seWka-7D8-9@gated-at.bofh.it>
The DMA_SG is still a type of memory copy operation that should
conform the hardware restriction. So this patch just applies the
copy_align to DMA_SG as well.
