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

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

From: Tomoki Sekiyama <[email protected]>

commit 523fc5c14f6cad283e5a266eba0e343aed6e73d5 upstream.

Removes allocation of coherent buffer for the control-request setup-packet
buffer from the yurex driver. Using coherent buffers for setup-packet is
obsolete and does not work with some USB host implementations.
