Just to clarify, the original patch change just the Telit FN990:
https://lore.kernel.org/netdev/CAMZdPi8gGrbkKnDR+WLadF92shJbwH-ksQY+dbpgfZ21iAp9ug@mail.gmail.com/

The problem is caused by the fact that it was merged two times and the
second time was merged wrongly.
The correct one is commit 479aa3b0ec2e000ac99dd0661936d9685d6cac64 and
the wrong one is 2d5253a096c6057bbf7caa5520856dcdf7eca8bb.
