From 884485e1f12dcd39390f042e772cdbefc9ebb750 Mon Sep 17 00:00:00 2001 From: Russell King - ARM Linux Date: Tue, 6 Mar 2012 22:34:46 +0000 Subject: dmaengine: consolidate assignment of DMA cookies Everyone deals with assigning DMA cookies in the same way (it's part of the API so they should be), so lets consolidate the common code into a helper function to avoid this duplication.
