Subject: dma-debug: use sg_dma_len accessor
X-Git-Tag: v2.6.31-rc1~408^2~6^2~2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=884d05970bfbc3db368f23460dc4ce63257f240d;p=pandora-kernel.git

dma-debug: use sg_dma_len accessor

debug_dma_map_sg() and debug_dma_unmap_sg() use length in struct
scatterlist while debug_dma_sync_sg_for_cpu() and
debug_dma_sync_sg_for_device() use dma_length. This causes bugs
warnings on some IOMMU implementations since these values are not
same; the length doesn't represent the dma length.

We always need to use sg_dma_len() accessor to get the dma length of a
scatterlist entry.
