The resource data in the network device is intended for ISA and other older busses, but not for PCI. Don't put PCI data there. Don't (ab)use the network device for keeping the IRQ number. Retire orinoco_pci_setup_netdev(), and print some minimal information to the kernel log instead, identifying the network device and the driver mostly to identify problems at startup. Scripts should rely on sysfs. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
