Quoting Eric Biggers <ebiggers@kernel.org>
I don't expect any problem with backporting this, but I don't see how this follows the stable kernel rules (Documentation/process/stable-kernel-rules.rst). I don't see what distinguishes this patch from ones that don't get picked up by AUTOSEL; it seems pretty arbitrary to me.

And I agree, this should not be in stable.
Best regards, Pavel
