Humm, interesting. I've no idea how this patch can trigger such a
warning. The USB gadget does not have an Ethernet PHY, let alone a
Microsemi 8530/40 Fast Ethernet PHY this patch adds.

However, it seems nicely documented how to reproduce this. Allan, can
you setup such a system? Reproduce it, then revert the change and see
if it still happens.
