Subject: [ 45/46] ioat: Fix DMA memory sync direction correct flag
Date: Thu, 24 Jan 2013 13:13:23 -0800	[thread overview]
Message-ID: <20130124211151.256678639@linuxfoundation.org> (raw)
In-Reply-To: <20130124211135.862755794@linuxfoundation.org>

3.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Shuah Khan <shuah.khan@hp.com>

commit ac4989874af56435c308bdde9ad9c837a26f8b23 upstream.

ioat does DMA memory sync with DMA_TO_DEVICE direction on a buffer allocated
for DMA_FROM_DEVICE dma, resulting in the following warning from dma debug.
Fixed the dma_sync_single_for_device() call to use the correct direction.
