------------------
From: Johan Hovold <johan@kernel.org>
commit dd5ca753fa92fb736b1395db892bd29f78e6d408 upstream.
Drop erroneous le16_to_cpu when returning the USB device speed which is
already in host byte order.
Found using sparse:
warning: cast to restricted __le16
Fixes: 946b960d13c1 ("USB: add driver for iowarrior devices.")
