3.5.7.26 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Thomas Pugliese <thomas.pugli...@gmail.com>
commit 7b6bc07ab554e929c85d51b3d5b26cf7f12c6a3b upstream.
For isochronous endpoints, set the RPIPE wMaxPacketSize value using
wOverTheAirPacketSize from the endpoint companion descriptor instead of
wMaxPacketSize from the normal endpoint descriptor.
