Subject: [PATCH v6 07/11] PCI: Replace pci_dev::driver usage that gets the driver name

struct pci_dev::driver holds (apart from a constant offset) the same
data as struct pci_dev::dev->driver. With the goal to remove struct
pci_dev::driver to get rid of data duplication replace getting the
driver name by dev_driver_string() which implicitly makes use of struct
pci_dev::dev->driver.

Acked-by: Simon Horman <simon.horman@...igine.com> (for NFP)
