[PATCH v4 02/12] omap_hsmmc: use original sg_len for dma_unmap_sg

From: Per Forlin <hidden>
Date: 2011-05-25 21:58:20
Also in: linux-mmc, lkml
Subsystem: multimedia card (mmc), secure digital (sd) and sdio subsystem, omap hs mmc support, the rest · Maintainers: Ulf Hansson, Linus Torvalds

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.
