Subject: [PATCH 00/10] Remove obsolete and orphaned wifi drivers
Date:   Mon, 23 Oct 2023 15:19:42 +0200
Message-Id: <20231023131953.2876682-1-arnd@kernel.org>
MIME-Version: 1.0

From: Arnd Bergmann <arnd@arndb.de>

As discussed previously, a lot of the older wifi drivers are likely
entirely unused, Though we can't know for sure.

As suggested by both Greg and Jakub, let's remove the ones that look
are most likely to have no users left and also get in the way of the
wext cleanup. If anyone is still using any of these, we can revert the
driver removal individually.

I would suggest merging these for net-next after 6.7-rc1 is out, to give
them the maximum amount of time for users to speak up before a release
comes out.

This kills off all pcmcia wifi drivers, and all wext users in
drivers/net/wireless, but not the ps3-gelic-wireless driver in
drivers/net/ethernet, or the staging drivers.

In staging, rtl8192u was already removed in the meantime, while rtl8712
and rtl8192e are apparently still used.  I have not been able to find
out whether ks7010 is still in use.

	Arnd
