No, it was first in 6.3:
| $ git log v6.3 | grep -A3 "commit 018584697533"

Please don't. The patch will only apply without modification
for v6.5+ because the function was moved to a different file.
As the only stable kernels in that range are 6.1 and 6.6 the
v6.5+ should be sufficient?

It is, see above.

I have an updated verion of the series almost ready that addresses
some of the AI review comments. Should I send an updated version or
incremental patches?

Best regards,
Christian
