How should we proceed with this patch?

Thanks,

ok, I see my mistake.
How do I specify a specific kernel version ?
Because this applies only to future 5.1.X, that aren't available yet.

Take a look at
https://www.kernel.org/doc/Documentation/process/stable-kernel-rules.rst

A "Fixes" tag also helps a lot.
