Neither are stable kernels fortunately, so any kernel >= 6.4 where both 
issues are present should be able to cleanly cherry-pick the change.

I suppose this should have called for me to issue two patches, one 
fixing lx-device-list-bus and the other one fixing lx-device-list-class, 
though it seems like this is such a niche usage that it may not matter 
that much.

They probably would, or I could submit a targeted fix for 6.3 for instance.
