From 3886ff5f63f33c801ed3af265ac0df20d3a8dcf5 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 30 Jun 2008 22:40:33 +0100 Subject: [PATCH] MMC: S3C24XX: Fix s3c2410_dma_request() return code check. 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.
