I have nothing against changing omapdss to use _GPL only. I've never
heard anyone using non-GPL panel drivers with omap.
Following these patch sets I can remove lots of the old code, which
contains the majority of the EXPORT_SYMBOLs in omapdss. I'll change
omapdss to use _GPL after that removal.

I don't think I understand what you mean then. What kind of macro are
you talking about?
