Just for my understanding, is it really necessary to get Acks from _all_
previous contributors?

I see that Thomas patches moving license texts into the kernel itself do not 
seem to have landed yet, but when the actual license text does _not_ change
and only its location to a common place inside the kernel sources, it feels
a bit overkill trying to get Acks from _everybody_ that contributed to
Rockchip devicetrees for the last 4 years.

If we would actually want to change the license I would definitly feel 
differently, but the license text does not change.


Thanks
