[PATCH RFC 17/51] DMA-API: block: nvme-core: replacedma_set_mask()+dma_set_coherent_mask() with newhelper

From: Russell King
Date: Thu Aug 01 2013 - 17:51:38 EST


Replace the following sequence:

dma_set_mask(dev, mask);
dma_set_coherent_mask(dev, mask);

with a call to the new helper dma_set_mask_and_coherent().
