However, sometimes some of the displays have been probed at that time, but not all. We can't return EPROBE_DEFER in that case, because then one missing driver would cause omapfb to defer always, preventing any display from working. However, if the user has defined a default display, we can presume that the driver for that display is eventually loaded. Thus, this patch changes omapfb to return EPROBE_DEFER in case default display is not found.
