So I don't think this part necessary to be changed. thanks, Takashi

'pci_set_dma_mask()' + 'pci_set_consistent_dma_mask()' can be replaced by an equivalent 'dma_set_mask_and_coherent()' which is much less verbose. With at it replace the 'card->dev' parameter passed to a 'dev_err()' call by an equivalent '&pci->dev' which is more consistent with the test just one line above.
