Thanks for clarifying this.

Right. I am not sure what will be the best tree to carry the testability 
changes. It seems that all of the IIO-tests in v5 will depend on the 
kunit stuff, and I think I will also include the DRM test fixes in this 
series as well just to keep things sorted in my mailbox. Anyways, I hope 
to finish the changes for v5 soon(ish) - maybe already Today and in any 
case during this week. I'll be CC:ing you and Brendan with (relevant 
patches of) v5 as well.

Yours,
