3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Thomas Pugliese <thomas.pugliese@xxxxxxxxx> 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.
