Or is that not the case? That was the case I seen, yes. Have old kernel running, dtbs building. Apply a patch. It starts behaving weird. You do make clean... but you still get old dtbs. (It would be nice if make socfpga_cyclone5.dtb would magically remove all the dtbs from old location; make dtbs does that if I understand stuff correctly).
