Hi Daniel.

While browsing this nice patch series I stumbled upon a detail.

This breaks build of arch/arm/mach-pxa/am200epd.c thats uses
FB_EVENT_FB_*REGISTERED:


       if (event == FB_EVENT_FB_REGISTERED)
                return am200_share_video_mem(info);
        else if (event == FB_EVENT_FB_UNREGISTERED)
                return am200_unshare_video_mem(info);


Found while grepping for "FB_EVENT" so this is not a build
error I triggered.
