Subject: [PATCH 4.7 124/143] USB: fix typo in wMaxPacketSize validation

4.7-stable 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.

Signed-off-by: Alan Stern <stern@...land.harvard.edu>
Fixes: aed9d65ac327 ("USB: validate wMaxPacketValue entries in endpoint descriptors")
