Subject: [PATCH 3/3] ARM: S3C64XX: Stop and flush requests on freeing
Date: Mon, 31 May 2010 13:34:43 +0200	[thread overview]
Message-ID: <4c67e6b3.487e0e0a.0a1b.22d7@mx.google.com> (raw)

When a DMA channel is freed, its pending requests should be flushed and the
channel should be halted. This patch ensures that happens.
