Subject: [ 11/32] USB: visor: fix initialisation of Treo/Kyocera devices

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

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

From: Johan Hovold <jhovold@...il.com>

commit 420021a395ce38b7ab2cceb52dee4038be7d8fa3 upstream.

Fix regression introduced by commit 214916f2e ("USB: visor: reimplement
using generic framework") which broke initialisation of Treo/Kyocera
devices that re-mapped bulk-in endpoints.
