DMA-API: provide a helper to setup DMA masks Many drivers contain code such as: dev->dma_mask = &dev->coherent_dma_mask; dev->coherent_dma_mask = MASK; Let's move this pattern out of drivers and have the DMA API provide a helper for it. This helper uses dma_set_mask_and_coherent() to allow platform issues to be properly dealt with via dma_set_mask()/ dma_is_supported(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
