** Description changed:

- When running artful on a new Zenbook Pro (uses Intel Wireless 8265), I
- get a hung shutdown with the message "wlp3s0: failed to remove key (1,
- ff:ff:ff:ff:ff:ff) from hardware (-22)". The kernel is also trying to
- load firmware versions that do not exist on the system i.e. versions 33
- then 32 of the firmware. It then seems to load version 31 of the
- firmware. Wireless features seem to work normally. The issues are just
- at shutdown time.
+ ===SRU Justification===
+ [Impact]
+ Message "wlp3s0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from
+ hardware (-22)" showed when the system shutdown.
+ 
+ [Test]
+ Users confirmed the patch fixes their issue.
+ 
+ [Regression Potential]
+ Low. It's in mainline Linux, limited to iwlwifi, trivial change.
