Subject: [PATCH 4/7] ARM: pass size to dma_free_coherent
Date: Fri, 29 Jul 2011 11:43:47 +0200	[thread overview]
Message-ID: <1311932630-5687-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1311932630-5687-1-git-send-email-s.hauer@pengutronix.de>

We'll need it later once we remap dma memory.
