Ubuntu's latest tag updated from v5.15.60 to v5.15.64 and one
advantage of them trailing upstream stable 5.15.y is that we can
backport fixes of fixes that got in with that commit range.
Found with the report of:
git log --decorate v5.15..v5.15.73 | \
~/gitdm/stablefixes --fixed-after v5.15.64 --regressed-before v5.15.64
