I'm happy to ack your patch but you have to send it correctly.
You are missing a changelog (although it ought to be small due
to the trivial change) as well as you SoB tag. Please consult
Documentation/process/submitting-patches.rst.

You also need to Cc akpm as he routes such areas to Linus.

Thanks,
Davidlohr
