Your patch is missing a Signed-off-by line in the commit-message. I can only accept patches with a Signed-off-by line in the commit-message like this: Signed-off-by: Your Real Name <email@your.domain> See: https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin Also your patch is malformed (it has been reflowed by your email client) and it does not apply properly. Since this is only a trivial single line change I've just manually recreated the patch myself, with me as author to avoid the S-o-b problem. I have given you credit by adding: Reported-by: Michał Szczepaniak <m.szczepaniak.000@xxxxxxxxx> to the commit message of the patch.
