[PATCH] sky2: use standard pci register capabilties for error register
Use the standard pci capability mechanism to access PCI express error registers, rather than hard coding the offset. Mask off the PCI express error from ever occuring on non-PCI express systems. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
