Subject: [PATCH 3.12 100/142] usb: musb: use new USB_RESUME_TIMEOUT

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

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

===============

commit 309be239369609929d5d3833ee043f7c5afc95d1 upstream.

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

Based on original work by Bin Liu <Bin Liu <b-liu@...com>>
