dma-mapping: pci: convert pci_set_dma_mask to call dma_set_mask
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. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Cc: James Bottomley <James.Bottomley@suse.de> Cc: David S.
