[PATCH] ARM: S3C64XX: Clear DMA flags on channel request

From: Charles Keepax <hidden>
Date: 2013-03-08 15:59:48
Also in: lkml
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

This patch clears the DMA flags when a DMA channel is requested. This is
necessary because otherwise the channel may inherit incompatible
settings from its last usage.
