[PATCH] PCI: automatically set device_driver.owner
A nice feature of sysfs is that it can create the symlink from the driver to the module that is contained in it. It requires that the device_driver.owner is set, what is not the case for many PCI drivers. This patch allows pci_register_driver to set automatically the device_driver.owner for any PCI driver. Credits to Al Viro who suggested the method.
