Can we expect to see this fix in the linux-generic-hwe-18.04 kernel at some point soon as well?

Without them iwlwifi cannot correctly recognize the device on systems with Comet Lake cpu. [Fix] These changes are cherry-picked from either mainline kernel or backport-iwlwifi. Firmware blob iwlwifi-QuZ-a0-jf-b0-*.ucode is also necessary. [Test] Verified on hardware 02f0:4234 with fw rev 48. [Regression Potential] Low. These changes includes only necessary changes to enable Intel Wireless-AC 9560. ====== Original Bug Description ====== Wireless module not detected by the system with the following error messages in the log: 00:14.3 Network controller [0280]: Intel Corporation Device [8086:02f0] Subsystem: Intel Corporation Device [8086:4030] ...
