From 5455a51e6f333d43e0b6b52d1712557475d8eb9d Mon Sep 17 00:00:00 2001 From: Graeme Gregory Date: Fri, 16 Mar 2007 17:11:43 +0100 Subject: [ARM] 4270/2: mach-s3c2443/irq.c off by one error in dma irqs This patch corrects an error when demuxing the DMA irq's DMA1 was used as a base and this should have been DMA0. Without this fix we do not process DMA0 irq's and the system effectively locks up in a loop trying the process the irq it never can.
