Because as this is written, it implies that not only DRM drivers with feature DRIVER_MODESET will not be available but also drivers with DRIVER_RENDER. But that's not the case, render-only drivers usually just ignore this parameter (but not all IIRC), so I wonder how we could make this comment more accurate. Also maybe we can mention in the comment fbdev and DRM? Just to make it clear that this will affect to both subsystems? When I first worked on this, there were a lot of assumptions in the stack (gdm, mutter, plymouth) that nomodeset basically meant "no DRM but fbdev".

Just to avoid the churn to require acks for all the drivers to merge this series?
Yes. It has no hurry, but we can do that. Best regards Thomas
The changes looks good to me. Reviewed-by: Javier Martinez Canillas <javierm@xxxxxxxxxx>
