This is most likely fixed by commit 29c6dd591bbd ("cdc-acm: fix NULL
pointer reference"). Which should defintely go into the 4.4 stable
series. Could you please add it to your v4.4 queue, David?
Ignore the "cdc-acm" prefix. The patch fixes a NULL pointer dereference
in the cdc_ether/rndis_host drivers introduced by commit 823bd3433424
("cdc-ether: switch to common CDC parser")
