[PATCH 2/4] PCI: Return -ETIMEOUT when reset readiness polling expires

[Richard Cheng]

pci_dev_wait() return -ENOTTY when the device fails to become ready. The
reset framekwork interprets this as an unsupported reset method and may
try another method.

Return -ETIMEOUT to report the timeout and stop reset-method fallback.
