-Subject: [PATCH] dwc_otg: only do_split when we actually need to do a
- split
-
-The previous test would fail if the root port was in fullspeed mode
-and there was a hub between the FS device and the root port. While
-the transfer worked, the schedule mangling performed for high-speed
-split transfers would break leading to an 8ms polling interval.
