From 31ab776ee952e5ef6e0a21be276686b84187fcaa Mon Sep 17 00:00:00 2001
From: Ben Dooks <ben-linux@fluff.org>
Date: Sun, 10 Aug 2008 09:29:14 +0100
Subject: [PATCH] The driver should be checking for a negative error code from
s3c2410_dma_request(), not non-zero. Newer kernels now return
the DMA channel number that was allocated by the request.
