Jesse's BIOS fb reconstruction code actually relies on the -ENOSPC return value to detect overlapping framebuffers (which the bios uses always when lighting up more than one screen). All this fanciness happens in intel_alloc_plane_obj in intel_display.c.
Since no one else uses this we can savely remove the WARN without repercursions.
