dma-mapping: pci: convert pci_set_dma_mask to call dma_set_mask
Browse files Browse the repository at this point in the history
This changes pci_set_dma_mask to call the generic DMA API, dma_set_mask.

pci_set_dma_mask (in drivers/pci/pci.c) does the same things that
dma_set_mask does on all the architectures that use pci_set_dma_mask;
calls dma_supprted and sets dev->dma_mask.  So we safely change
pci_set_dma_mask to simply call dma_set_mask.
