Because you develop on ancient, 10 year old downstream kernel?

You really do not try enough and this is just wasting our time.

Please think and really carefully check your replies. What prefix do you
have in compatible? This command:
git grep tesla, | wc -l

gives '99' results including obviously vendor prefix.

So your warning is basically impossible or your code is just broken.
Don't just ask maintainers on every little trouble you have. You must
debug it. Not we.

Best regards,
