s/that/whose visibility/?

As far as I can see what suffices for menuconfig is that the visibility
of an item is influenced by that menu's symbol. Whether that item is
actually not set at all (the depends on case) or only not visible (the
"prompt" if EXPERT case) doesn't matter here.

Provided you somehow tweak the commit explanation to reflect my remark:
