PCI: pciehp: ignore undefined bit in link status register
Bit 10 in Link Status register used to be defined as Training Error in the PCI Express 1.0a specification. But it was removed by Training Error ECN and is no longer defined. So pciehp must ignore the value read from it. Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
