From: Greg Kroah-Hartman
Date: Wed Aug 09 2017 - 16:59:38 EST


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

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

From: Oliver Neukum <oneukum@xxxxxxxx>

commit 60bcabd080f53561efa9288be45c128feda1a8bb upstream.

This fixes the oops discovered by the Umap2 project and Alan Stern.
The intf member needs to be set before the firmware is downloaded.
