From 89cb7e7fd6c0917bb9236ea48bf538d4668ed009 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 3 Feb 2009 16:28:48 -0800 Subject: Revert Staging: at76_usb: update drivers/staging/at76_usb w/ mac80211 port Reverts 02227c28391b5059a7710d6039c52912b0ee2c1d (Had to be done by hand due to other patches that had come after this.) Turns out that we don't want the mac80211 port of this driver just yet, as there is a different driver working on adding this support. So keep things old and different for now. This is being reverted at the request of the linux-wireless developers. Cc: Kalle Valo Cc: John W.
