I suppose that's OK, although I prefer "depends" rather than "select".

I tracked down one of the problems that I was seeing:

net/wireless/wext-priv.c:206: error: implicit declaration of function 'call_commit_handler'

with:
# CONFIG_WIRELESS is not set
CONFIG_WIRELESS_EXT=y
CONFIG_WEXT_PRIV=y

This is being caused by several drivers in drivers/staging/ doing
	select WEXT_PRIV
without using either enough dependencies or even more (ugly) selects.
(or just because kconfig isn't sufficient)
