[PATCH] ALSA: emu10k1: Use dma_set_mask_and_coherent to simplify code
'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.

It's a good cleanup, but ...

... this will make it inconsistent with other error message lines in the same function, OTOH. So I don't think this part necessary to be changed.
thanks,
