DMA ops are a helper for architectures and not for drivers to override the DMA implementation. Unfortunately driver authors keep ignoring this. Make this more clear by renaming the symbol to ARCH_DMA_OPS, have the three drivers overriding it depend on that. They should probably also be marked broken, but we can give them a bit of a grace period for that. Signed-off-by: Christoph Hellwig <hch@lst.de>
