Maxime -

I'm cutting a lot of context here. Not because I don't think it deserves
an answer, but because I seem to be failing at communication.

With that, do you mean a dumb struct device, or any struct device with a
suitable lifetime, that we'd pass to devm_drm_panel_alloc()?

Is using devm_drm_panel_alloc() like that instead of our own allocation
with drm_panel_init() the main point of contention for you? If yes, we
can do that.

BR,
Jani.
