Subject: [PATCH] dmaengine: fix memleak in dma_async_device_unregister
Date: Tue, 26 Jan 2010 10:26:06 +0100	[thread overview]
Message-ID: <1264497966-23688-1-git-send-email-agust@denx.de> (raw)

While debugging a dma driver I noticed a memleak after
unloading the driver module.

Caught by kmemleak.
