Good luck with that. To quote
https://docs.kernel.org/process/handling-regressions.html :

```
Regarding stable and longterm kernels:

[...]

* Whenever you want to swiftly resolve a regression that recently also
made it into a proper mainline, stable, or longterm release, fix it
quickly in mainline; when appropriate thus involve Linus to fast-track
the fix (see above). That's because the stable team normally does
neither revert nor fix any changes that cause the same problems in mainline.
```

Note the "normally" in there, so there is a chance.

Ciao, Thorsten
