cherry-picking the one patch is not enough. The -next branches are too
far apart to start applying ADL-S patches in either branch. Doing so
will lead to way too bad merge conflicts.
Which just means the cherry-pick won't help, as you'll need a topic
branch with a sensible baseline to merge the ADL-S support to both
branches. Now the merge-base is too far away.

Mmmh, I tested this, but can't reproduce now. Never mind. *shrug*.

Please let's first get the branches back in sync, and then create a
topic branch for ADL-S, and merge it to both. Everything else will lead
