The broader context of the private mail was about you stepping back on kernel
development. You did so with a few more details (which I'm not going to
disclose), that made it clear to me that you don't want to be bothered with
kernel development any more.

In combination with you giving permission to "use it/submit it in any way", I
thought it's better to just pick a safe path to not misrepresent you given all
the changes I made.

I do still credit you on all corresponding patches though.

Except drm_legacy_fields! and VTABLE (which is just trival boilerplate code)
device.rs changed fundamentally, i.e. I switched the device abstraction to use
the subclassing pattern.

If you look further you will find that I really changed a lot of things.

I have *nothing* to hide, here's the overall diff for all the changes I made:

You just said you "don't have the spoons to make some deep analysis here" and
right below you acuse me of just "moving code around".

Which means that you do so *without* evidence. And again, I have *nothing* to
hide, see [1].

Besides that I also told you that I'm fine to change primary authership, if you
tell me where you think it would be appropriate (even though I do think my
changes do justify how things are currently).

> I'm just disappointed.

That's where you are maneuvering *yourself* into.

You could have easily just asked me to change things for patch #X, #Y and #Z.

Instead you outright started with accusing me of things. I also feel like you
intentionally try to misrepresent what I am doing and what my intentions are.

I neither have the time, nor am I willing to deal with random drama like this.

If you want something changed, just go ahead and tell me what, *without* more
drama and without more accusing me of things.
