[PATCH] file_storage and UHCI bugfixes
The patch below (as547) corrects two minor errors, one in the
file_storage gadget driver (need to send a length-zero packet if a
control response is short) and one in the alternate UHCI driver (need
to set the QH bit in the frame list). Both of these are back-ports of
things that have been in 2.6 for several releases.
