    #define pci_register_driver(d) __pci_register_driver(d, THIS_MODULE)

    #define ide_pci_register_driver(d) __ide_pci_register_driver(d, THIS_MODULE)

    __pci_register_driver(drv, module) - same as current pci_register_driver(),
    except that instead of
    drv->driver.owner = drv->owner;
    it does
    drv->driver.owner = module;

    __ide_pci_register_driver(driver, module):
    return __pci_register_driver(driver, module);
    driver->driver.owner = module;
    list_add_tail(&driver->node, &ide_pci_drivers);
    return 0;

    and in ide_scan_pcibus() turn
    __pci_register_driver(d, d->driver.owner);

    Update exports (i.e. export __pci_register_driver and __ide_pci_register_driver
    instead of pci_register_driver and ide_pci_register_driver resp.).

    At which point pci_driver->owner become unused and can be killed at leisure.
