Of which there are clearly none, as can be seen by the node not being referenced by any other one. I can add that to the commit message. This is actually as bisectable as it gets, since it goes out of the way to satisfy both compilation and dt-bindings checks > Should be the last patch,> not the first, with explicit notice that it must wait after the next > merge window. Patches to all three subsystems can go in independently to their respective trees (except maybe icc bindings going in before dts could spawn a dt-checker warning) > Plus this affects all outside users, which also should be somehow > explained.

Yes and no, you're focusing on me referencing a different commit while I included the same rationale it presents later in the sentence. Konrad
