I tend to as well, but in this case the WIRELESS itself is just an
option that makes other options invisible, it's not used elsewhere, and
as such I think this is ok -- why hide the wireless drivers unless the
user first selects the wireless core options?

OTOH, you already need to select cfg80211/mac80211 for most drivers, so
I suppose "depends on WIRELESS" would be ok too.

Hah, staging/, well, that's kinda hard to solve I guess. Except by
fixing all the staging/ drivers to depend on WIRELESS too, like the
patch would do for the regular drivers.

I think you can get the same effect now with the non-staging drivers.
I'll submit this patch formally and ask John to include it, and staging/
can just depend on WIRELESS.
