Hello,
removing my usb-modem (option icon 226) i get this oops (i attached the dmesg output):

BUG: kernel NULL pointer dereference, address: 0000000000000068

reverting this patch fix the problem on detaching the modem:

https://marc.info/?l=linux-usb&m=161781851805582&w=2

I'm not a developer, i hope the attached dmesg.txt will suffice
