Subject: [PATCH 5/9] ata: Use dma_alloc for buffer
Date: Thu, 6 Dec 2012 14:34:26 +0100 [thread overview]
Message-ID: <1354800870-28385-6-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1354800870-28385-1-git-send-email-s.hauer@pengutronix.de>
ATA devices using DMA may need a sufficiently aligned buffer, so use
dma_alloc instead of regular malloc.
