Uh? I've been sending a couple whole subsystem refactorings touching
every driver a couple times a year for what, 5 years now?
There are still more that are needed, like trying to redo the drvdata
apparently. As well as stuff on the ops side, and more and more.
Granted you are looking at it after all this work, but there are still
problematic areas. drvdata, some of the ops, some of the locking, I
think there will be alot of C work to fix things up enough rust
bindings can happen sanely.
It is not so easy, your LLM looks like it put PM trampolines in every
driver, which I would not like to see.. Not sure how it solved vga
without touching drm..
