Why?  This says what happened, which you can see from the patch itself,
but it does not say why this is needed at all.

Also, you sent 4 patches, without any numbering, so I have no idea what
order to apply them in.

Please fix the changelog entries up and send this as a patch series so
that I can correctly apply them.

thanks,

We will fix this.

They are all independent that's why I have sent them separately as
single patches.

Thanks,
