You are right, me idiot, error will happen only upon try to make use of
of_get_fb_videomode() (defined in this patch) in the da8xx-fb driver
(with da8xx_omapl_defconfig), to be exact upon adding,

"video: da8xx-fb: obtain fb_videomode info from dt" of my patch series.

The change as I mentioned or something similar would be required as
any driver that is going to make use of of_get_fb_videomode() would
break if CONFIG_OF_VIDEOMODE or CONFIG_FB_MODE_HELPERS is not defined.

And testing was done over v3.8-rc2.

Now I realize it is.
