X-Git-Tag: v2.6.38-rc1~454^2~13

spi/pl022: pass the returned sglen to the DMA engine

The sglen return by the dma_map_sg() should be passed to the DMA
engine, not the one passed in. If we one day have a DMA mapper
that can coalesce entries, this will bug due to a too large
number of entries being passed in.
