    This is how DRM does it...

    for (i = 0; driver->pci_driver.id_table[i].vendor != 0; i++) {
    pid = (struct pci_device_id *)&driver->pci_driver.id_table[i];

    pdev = NULL;
    /* pass back in pdev to account for multiple identical cards */
    while ((pdev =
    pci_get_subsys(pid->vendor, pid->device, pid->subvendor,
    pid->subdevice, pdev)) != NULL) {
    /* stealth mode requires a manual probe */
    pci_dev_get(pdev);
    drm_get_dev(pdev, pid, driver);
    }
    }
    return 0;
