Subject: [RFC 2/2] iwmc3200top: remove driver for unavailable hardware
From: "John W. Linville" <linville@...driver.com>
This hardware never became available to normal humans. Leaving this
driver imposes unwelcome maintenance costs for no clear benefit.

If there are no objections, I'll push this series through the
wireless-next tree along with the iwmc3200wifi removal.
