There are others. For my config, I have:

{*} Support for frame buffer devices  --->
<M> OMAP2+ Display Subsystem support  --->
[ ] Exynos Video driver support  ----
< > Solomon SSD1307 framebuffer support

I didn't want to start fixing those at the moment, as I have no idea
about exynos or solomon, and I wanted to just try to do the reorder,
without any other changes.

I agree that there's something wrong with the items. For the OMAP DSS,
there are non-fbdev related items under that menu, used also by omapdrm.
So it should probably be split into different components.

Ok, fixed.

Thanks. After pushing this to for-next, I'm getting compile error
reports from Fengguang and Stephen. Let's see if I manage to avoid
those... This is not the easiest change to manage.
