Subject: [PATCH v4 02/12] omap_hsmmc: use original sg_len for dma_unmap_sg
Date: Wed, 25 May 2011 23:57:23 +0200 [thread overview]
Message-ID: <1306360653-6196-3-git-send-email-per.forlin@linaro.org> (raw)
In-Reply-To: <1306360653-6196-1-git-send-email-per.forlin@linaro.org>
Don't use the returned sg_len from dma_map_sg() as inparameter
to dma_unmap_sg(). Use the original sg_len for both dma_map_sg
and dma_unmap_sg.
