that simply doesn't always work; for example I started with a minimal d=
efconfig
and want to enable SENSORS_APPLESMC, from nconfig I can search this one
get it depends HWMON && INPUT, if the current .config doesn't have HWMO=
N
and I just write SENSORS_APPLESMC=3Dm there, the following rebuild will=
 deselect
SENSORS_APPLESMC actually;

I am asking a config method that accepts a list of config items (or mod=
ule names),
let it make sure all depended items also be selected?
