In commitfce35bce0f("config: support new symbol intro'd in kernel 4.12") I forgot to remove the initial debug test line. This clearly is wrong as the same symbol is defined conditionally in the line below as it should be. I looked over it as I just checked if the symbol was present now upon testing it.
