WiFi doesn't work after kernel update 6.2.+, even though it should work according to this commit: https://github.com/torvalds/linux/commit/9695dc2e4be90315471ea4c672836929f5c403fe

Steps to reproduce (if you know):

Expected behavior: The WiFi driver is loaded, and the WiFi works.

Other Notes: I am sorry if this is the wrong place for this issue.

I tested the same WiFi card on Ubuntu 23.04 beta today, and it works perfectly. I acquired the ISO image from the official Ubuntu website https://releases.ubuntu.com/lunar/. The beta uses kernel 6.2., which is lower than the kernel Pop!_OS currently uses (6.2.6-76060206-generic).
