It seems that Ubuntu has not backported the second part too:
http://changelogs.ubuntu.com/changelogs/pool/main/l/linux/linux_5.15.0-58.64/changelog
 only mentions the first part.

I guess this is due the fact that the commit message is named "fix build 
warning" and did nit received much attention.

I will open an issue with Ubuntu.

thanks
