From: Johannes Berg Date: Tue, 6 Dec 2011 19:45:37 +0000 (+0100) Subject: wireless: disable wext sysfs by default X-Git-Tag: v3.3-rc1~182^2~44^2~204 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0052d812599fb0327792b6c3f4257b26dcc13239;p=profile%2Fivi%2Fkernel-x86-ivi.git wireless: disable wext sysfs by default This code has been on the list to remove for a long time, so disable it by default, add a warning to its Kconfig, and schedule it for removal in 3.5. The only known dependency, hal, has not required it since its 0.5.12 release, which was in early 2009 and hal has since been deprecated completely. Signed-off-by: Johannes Berg Signed-off-by: John W.
