[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.
