Minor nit: the shortlog should be in double quotes.
I fixed it up manually, so nothing you need to do, but just for future
reference.
This was found by some automated checking recently added to the
linux-next tree.

Thanks: I will follow the protocol next time.
As pointed my Martin on Odroid C1+ my patch do not fix complete issue.
[0] https://patchwork.kernel.org/patch/10761371/
[1] https://patchwork.kernel.org/patch/10761375/
Both of my patch seem to be wrong and if possible please so drop them
from linux-next and your fix tagged.
I will try to find proper fix proper to the issue.
Quick phy driver and dts changes enable *Bus 01.Port 1* and *Bus 02.Port 1*
[alarm@archl-c2m ~]$ lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=dwc2/1p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 1: Dev 5, If 0, Class=Mass Storage, Driver=usb-storage, 480M
|__ Port 2: Dev 3, If 0, Class=Video, Driver=uvcvideo, 480M
|__ Port 2: Dev 3, If 1, Class=Video, Driver=uvcvideo, 480M
|__ Port 2: Dev 3, If 2, Class=Audio, Driver=, 480M
|__ Port 2: Dev 3, If 3, Class=Audio, Driver=, 480M
|__ Port 3: Dev 4, If 0, Class=Vendor Specific Class, Driver=, 480M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc2/1p, 480M
Need to fix the vbus setting for both the bus ports, which I am looking into.
Best Regards
