[PATCH] Pass struct dev pointer to dma_cache_sync()
Pass struct dev pointer to dma_cache_sync() dma_cache_sync() is ill-designed in that it does not have a struct device pointer argument which makes proper support for systems that consist of a mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync to take a struct device pointer as first argument and fix all its callers to pass it.
