From 50b9773c13bffbef32060e67c4483ea7b2eca7b5 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 27 Jun 2018 12:33:56 +1000 Subject: usb: gadget: Fix OS descriptors support The current code is broken as it re-defines "req" inside the if block, then goto out of it. Thus the request that ends up being sent is not the one that was populated by the code in question. This fixes RNDIS driver autodetect by Windows 10 for me. The bug was introduced by Chris rework to remove the local queuing inside the if { } block of the redefined request.
