[PATCH 3.19 068/177] usb: musb: use new USB_RESUME_TIMEOUT

From: Greg Kroah-Hartman
Date: Sat May 02 2015 - 15:30:48 EST


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

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

From: Felipe Balbi <balbi@xxxxxx>

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@xxxxxx>>
