mips,unicore32: swiotlb doesn't need sg->dma_length
Only mips and unicore32 select CONFIG_NEED_SG_DMA_LENGTH when building swiotlb. swiotlb itself never merges segements and doesn't accesses the dma_length field directly, so drop the dependency. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: James Hogan <jhogan@kernel.org>
