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

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

From: Dinh Nguyen <Dinh.Nguyen(a)freescale.com>

commit 88e3b59b5adce5b12e205af0e34d518ba0dcdc0c upstream.

The max packet length bit mask used for isochronous endpoints
should be 0x7FF instead of 0x8FF. 0x8FF will actually clear
higher-order bits in the max packet length field.

This patch applies to 2.6.34-rc6.
