I'm unable to select that config option .

I double checked my config file - with the information from "make menuconfig" :

 Symbol: IWLWIFI_DEBUGFS [=n]
 Type  : boolean
 Prompt: iwlagn debugfs support
   Defined at drivers/net/wireless/iwlwifi/Kconfig:72
   Depends on: NETDEVICES [=y] && WLAN [=y] && IWLAGN [=m] && MAC80211_DEBUGFS [=n]
   Location:
     -> Device Drivers
       -> Network device support (NETDEVICES [=y])
         -> Wireless LAN (WLAN [=y])
           -> Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlagn)  (IWLAGN [=m])
             -> Debugging Options


it looks all good (.config attached) - but the option itself isn't included in the kernel config file nor I can select it :-(
