Cardbus devices fail probe with error -5 due to NULL archdata.dma_ops.

For example in sata_sil.c function sil_init_one

    rc = pci_set_dma_mask(pdev, ATA_DMA_MASK);

which returns -5 (-EIO) because

get_dma_ops(&pdev->dev);

returns NULL.

Adding set_dma_ops(dev, &dma_direct_ops) to the driver fixes the problem, but I don't know if that is the right place to add the call or if that is multi-platform appropriate. Perhaps the cardbus bridge (yenta) should have the call?


I think this is the same as https://bugs.launchpad.net/ubuntu/+bug/421940 except that it is a rt2500 card.

Also http://bugzilla.kernel.org/show_bug.cgi?id=14121 except that it is for ath5k.
