Are you saying that the driver and the bindings should be the same commit after all? Are you saying something else? I’m afraid I still don’t understand what you mean by this, but I want to, and I’m trying to.

They come as one patchset. Separate patches, one patchset. Otherwise you
get checkpatch errors, right?

Yes. Do not strip some lists based on your preference. Why only some
people should receive this, not everyone involved in the subsystem?

All recent submissions follow this, so the best is to take last commits.

This is very difficult to respond. Please use inline comments, I have no
clue which part you are now commenting. This is not mailing list style
response.
