Hi! We have already discussion about it, search for older email with 
Message-Id: <201601231357.32629@pali>

After that in June, Bin wanted from me to resend patch with changed 
subject... but after that I forgot. Now I resent it.

What I meant is that the patch description is missing :)

I don't accept patches without any changelog information, nor would I
ever expect any other maintainer to do so. Please read
Documentation/SubmittingPatches for how to write a good changelog
message.

thanks,
