Revert "PCI: Remove struct pci_dev->driver"
This reverts commit b5f9c644eb1baafcd349ad134e2110773f8d0a38. Revert b5f9c644eb1b ("PCI: Remove struct pci_dev->driver"), which is needed to revert 2a4d9408c9e8 ("PCI: Use to_pci_driver() instead of pci_dev->driver"). 2a4d9408c9e8 caused a NULL pointer dereference reported by Robert Święcki. Details in the revert of that commit. Fixes: 2a4d9408c9e8 ("PCI: Use to_pci_driver() instead of pci_dev->driver") Link: https://lore.kernel.org/linux-i2c/CAP145pgdrdiMAT7=-iB1DMgA7t_bMqTcJL4N0=6u8kNY3EU0dw@mail.gmail.com/ Reported-by: Robert Święcki <robert@swiecki.net> Tested-by: Robert Święcki <robert@swiecki.net> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
