Subject: [PATCH 3.2 081/152] USB: fix typo in wMaxPacketSize validation

3.2.84-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Alan Stern <stern@...land.harvard.edu>

commit 6c73358c83ce870c0cf32413e5cadb3b9a39c606 upstream.

The maximum value allowed for wMaxPacketSize of a high-speed interrupt
endpoint is 1024 bytes, not 1023.
