[PATCH] orinoco: reduce differences between PCI drivers, create orinoco_pci.h
Make all Orinoco PCI drivers (orinoco_pci, orinoco_plx, orinoco_tmd and orinoco_nortel) as similar as possible. Use the best implementation of error handling, the best error messages, the best comments. Put common code to orinoco_pci.h. For now, it's suspend and resume functions and function for registering the network device. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
