Subject: dma-mapping: pci: move pci_set_dma_mask and pci_set_consistent_dma_mask to pci-dma... 
X-Git-Tag: firefly_0821_release~9833^2~2636
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5f3cd1e0bb452c31a306a3e764514ea2eaf7d2e0;p=firefly-linux-kernel-4.4.55.git

dma-mapping: pci: move pci_set_dma_mask and pci_set_consistent_dma_mask to pci-dma-compat.h

We can use pci-dma-compat.h to implement pci_set_dma_mask and
pci_set_consistent_dma_mask as we do with the other PCI DMA API.

We can remove HAVE_ARCH_PCI_SET_DMA_MASK too.
