From 0ca3ff10db648a38b0aeb219a19980fec6ae5135 Mon Sep 17 00:00:00 2001 From: Russell King - ARM Linux Date: Tue, 6 Mar 2012 22:34:06 +0000 Subject: dmaengine: move last completed cookie into generic dma_chan structure Every DMA engine implementation declares a last completed dma cookie in their private dma channel structures. This is pointless, and forces driver specific code. Move this out into the common dma_chan structure.
