So it tells us ("depends on" vertical, "is selected by" horizontal):

                                  R8723AU -> RFKILL
                                   |
                                   v
              MOUSE_APPLETOUCH -> USB
                |
                v
ACPCI_CMPC -> INPUT
  |
  v
RFKILL

doesn't it? And why is that a problem?
