John W. Linville 143d40f3ab Revert "ipw2200: fix oops on missing firmware" ... This reverts commit e6c5fc53d0. Based on this regression report: Date: Thu, 05 Nov 2009 15:59:16 +0100 From: Holger Schurig <holgerschurig@gmail.com> To: linux-wireless@vger.kernel.org Subject: BUG: oops when "rmmod ipw2200" This happened on wireless-testing v2.6.32-rc6-41575-g5e68bfb. I modprobed ipw2200, put it into monitor mode, used tshark a while to monitor, then I stopped tshark, "ifconfig eth2 down" and finally "rmmod ipw2200", and voila: [ 917.189620] ------------[ cut here ]------------ [ 917.189717] kernel BUG at net/wireless/core.c:543!
