From b203bd3f6b9c3db3b1979c2ff79bb2b9be8f03a3 Mon Sep 17 00:00:00 2001 From: Ira Snyder Date: Thu, 3 Mar 2011 07:54:53 +0000 Subject: [PATCH] dmatest: fix automatic buffer unmap type The dmatest code relies on the DMAEngine API to automatically call dma_unmap_single() on src buffers. The flags it passes are incorrect, fix them. Signed-off-by: Ira W.
