Gentle ping.

Any comments on this commit?
For me the referenced commit causes a regression. If I understand it
correctly it will do so for any user which uses the devicetree.bbclass
and did set S to anything other than WORKDIR.

I think this should be fixed here rather than any recipe which sets S
also setting UNPACKDIR.

Thanks.
