This patch fixes the issue which was observed while transfering a large file ( > 20MB) over USB (OMAP MUSB controller acts as USB host) to an attached USB thumb drive. It was found that CDB field of CBW packet was set to 0x0. This was due to missing a barrier before DMA engine starts transfer. This buffer is allocated using dma_alloc_coherent which gives non-cacheble but bufferable memory and hence needed a write memory barrier to flush the write buffer.
