Subject: [PATCH 3.13.y-ckt 45/95] usb: host: oxu210hp: 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 84c0d178eb9f3a3ae4d63dc97a440266cf17f7f5 upstream.

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