I guess it woulod make sense, that patch could go in right away without
any further discussion, so it also reduces the code that's still being
discussed?

My bad, will double check.

Subject: [PATCH] wireless: allow Atheros card to not depend on ath.ko
To: John W. Linville <[email protected]>,

There are 2 different things:
- sub-menu for "Atheros Wireless cards" family
- module ath.ko with common Atheros code

Until now, they both used to depend on the same Kconfig variable ATH_COMMON.
Thus, being "Atheros card" and "depending on ath.ko" was the same.

To allow module to belong to the
"Atheros Wireless cards" family but not use ath.ko,
2 conditions above need to be separated.

So, this patch introduce new Kconfig variable ATH_CARDS for belonging
to the "Atheros Wireless Cards" family; while ATH_COMMON becomes hidden
variable to express dependency on common Atheros code in ath.ko. Modules
that depend on this common code now express it by setting ATH_COMMON.
