From b62cfc5e0e59d1e0192105144b724b0c332720a0 Mon Sep 17 00:00:00 2001 From: Rafal Prylowski Date: Sat, 26 Nov 2011 12:54:07 +0200 Subject: [PATCH] dma/ep93xx_dma: fix initialization of M2M control register Setting the flags in case of IDE didn't have any effect since the control register is overwritten few lines below. So move these to be after the control register is initialized.
