Public bug reported:

I get unexpected symbol versioning errors on loading a WiFi module, both
built-in and external:

This is the built-in version:

That looks like to me a packaging error, but then I compiled also an unofficial 
version of the driver from sources:

petal# git remote -v
origin  https://github.com/lwfinger/rtw88 (fetch)
origin  https://github.com/lwfinger/rtw88 (push)
petal# ls -ld rtw_8821ce.ko

retpoline:      Y
name:           rtw_8821ce
vermagic:       6.8.0-22-generic SMP preempt mod_unload modversions 

So I rebooted into kernel 5.15.0-102 and 'rtw88_8821ce' seems to work as
always:

petal# modprobe rtw88_8821ce
petal# dmesg | tail -3
[81954.635875] rtw_8821ce 0000:01:00.0: sta 22:b0:01:a8:1e:4b with macid 0 left
[81954.736381] rtw_8821ce 0000:01:00.0: stop vif 60:e9:aa:a7:9d:31 on port 0
[81984.525318] rtw_8821ce 0000:01:00.0: Firmware version 24.11.0, H2C version 12

I tried to use '--force-vermagic' and '--force-modversion' to see what
would happen and 'modprobe' failed in  both cases.

My guess is that there is something quite weird going on with 'linux-
modules-extra-6.8.0-22-generic' because compiling from source an out-of-
kernel module should not have any such issues.
