Subject: [PATCH 3.13.y-ckt 50/95] usb: core: hub: use new USB_RESUME_TIMEOUT

3.13.11-ckt21 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felipe Balbi <balbi@...com>

commit bbc78c07a51f6fd29c227b1220a9016e585358ba upstream.

Make sure we're using the new macro, so our
resume signaling will always pass certification.
