Hi,
On my Lenovo X1 Carbon gen 5 system,after I upgraded to v4.17-rc1
iwlwifi started to fail with following splats on dmesg:

The controller in question is:
04:00.0 Network controller [0280]: Intel Corporation Wireless 8265 / 8275
[8086:24fd] (rev 88)
Bisection pointed to the following commit and after I reverted it,
things seem to work fine again:
66fa2424df16 ("iwlwifi: fw api: support the new scan request FW API version")
Any idea what might be wrong with that commit and how to fix it
properly?
Thanks!
