> sparc has two dma_set_mask implementations for 32bit and 64bit. They
> are same except for the error returned value. We can safely unify them
> since the error returned value doesn't matter as long as it is

> This patch also changes dma_set_mask not to call
> pci_set_dma_mask. Instead, dma_set_mask does the same thing that
> pci_set_dma_mask does. This change enables ut to change
> pci_set_dma_mask to call dma_set_mask; we can implement
> pci_set_dma_mask as pci-dma-compat.h does.
