I see that the issue is present since the super speed plus support
is added to this driver. I will add the below commit in the Fixes
tag and send the v2.

commit 90c4d05780d47e14a50e11a7f17373104cd47d25

    usb: fix various gadgets null ptr deref on 10gbps cabling.

    This avoids a null pointer dereference in
    f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm}
    by simply reusing the 5gbps config for 10gbps.

Thanks,
Pavan
