Rpi3: no ethernet in 4.13: bisected to patch 'USB: of: fix root-hub device-tree node handling'

[Hans Verkuil]

When testing with my Raspberry Pi 3 and the 4.13-rcX mainline kernel
I discovered that there was no ethernet. After bisecting I got to commit
2bf69867 ('USB: of: fix root-hub device-tree node handling').

With that commit lsusb outputs:

rpi3: ~ # lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

After reverting just that commit (I'm on 4.13-rc3 now) ethernet is
restored and lsusb gives me:

rpi3: ~ $ lsusb
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I don't speak USB, so I have no idea why this patch causes these issues,
but I am happy to test patches.

Regards,
