Pull PCI fixes from Bjorn Helgaas:
 "Revert conversion to struct device.driver instead of struct
  pci_dev.driver.

  The device.driver is set earlier, and using it caused the PCI core to
  call driver PM entry points before .probe() and after .remove(), when
  the driver isn't prepared.

  This caused NULL pointer dereferences in i2c_designware_pci and
  probably other driver issues"
