Which driver a device is bound to is available twice: In struct

duplication introduce a wrapper to access struct pci_dev's driver

calculate the driver using pci_dev::dev->driver.

 #define	to_pci_driver(drv) container_of(drv, struct pci_driver, driver)

Seems like above is (mis)using TAB instead of space after #define. Not sure if
it's good to have them different.
