Agreed. :) I am not an expert in DSS.

Perhaps you are using some old kernel? As mentioned in the cover letter, we get this error only if 2/2 is applied and 1/2 is not applied. I tested this by applying 2/2 on v3.0-rc4 and using omap2plus_defconfig. > > Tomi > >

In certain board files, there are references to vram related functions which are defined in drivers/video/omap2/vram.c. Because of this direct dependency, CONFIG_FB_OMAP2 should be a built-in feature. As per the current architecture, CONFIG_FB_OMAP2 is dependent on CONFIG_OMAP2_DSS. Hence CONFIG_OMAP2_DSS support should also be selected by default.
