Christoph Hellwig e0c6584df9 sh: make dma_cache_sync a no-op ... sh does not implement DMA_ATTR_NON_CONSISTENT allocations, so it doesn't make any sense to do any work in dma_cache_sync given that it must be a no-op when dma_alloc_attrs returns coherent memory. On the other hand sh uses dma_cache_sync internally in the dma_ops implementation and for the maple bus that does not use the DMA API, so a the old functionality for dma_cache_sync is still provided under the name sh_sync_dma_for_device, and without the redundant dev argument. While at it two of the syncing dma_ops also go the proper _for_device postfix.
