You treat my feedback selectively... some things improved, but not
everything. I am literally repeating the same and expect different
results from you... isn't that the definition of insanity?
Let me paste ignored parts:
1. Your patches are still not correctly threaded. There is no threading
at all.
I said it multiple times. What else should I say here?
2. Subject: ASoC: dt-bindings: Add tas2781 amplifier
(drop the full stop - why did you add it there?)
3. Missing changelog under ---.
I mentioned it already few times, didn't I?

Drop the reference to gpio.txt.
I give up. I spent too much time on it while being also ignored a bit
too much.
