Purely optional refactor idea, since you're not the first one to stumble
over this, and in hindsight it makes sense to have these functions as the
defaults:
- Move all the set_property legacy2atomic helper functions into the core,
renaming them to e.g. drm_atomic_default_crtc_set_property. But we'd do
this for connectors and planes too ofc.
- Use them as the default handler if drm_drv_uses_atomic_modeset() is
true.
- Nuke the default assignment from all drivers.
This way there's less boilerplate, less confusion (some people thought you
must have atomic userspace to use atomic properties, which isn't true as
long as this is wired up) and happier driver developers :-)
But since you've volunteered already to fix the fbdev clut stuff this
really is just an idea.
