ide: keep pointer to struct device instead of struct pci_dev in ide_hwif_t
Keep pointer to struct device instead of struct pci_dev in ide_hwif_t. While on it: * Use *dev->dma_mask instead of pci_dev->dma_mask in ide_toggle_bounce(). There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
