As some other issues are blocking that patch series, can this change be merged independent of that patch series via USB tree? The original change can be seen at http://marc.info/?l=linux-usb&m=136203353205291&w=2 Thanks, Venu -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
