From: Johannes Berg Date: Mon, 8 Sep 2008 15:44:23 +0000 (+0200) Subject: mac80211: use sdata pointer for scan interface X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=491775a50787b9fbb09b5735be3d111c65935f5c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mac80211: use sdata pointer for scan interface Since we now use sdata pointers most of the time, using a netdev pointer here is somewhat artificial, use an sdata pointer instead. Replace a netdev-prefix in a few messages by a wiphy-prefix. Signed-off-by: Johannes Berg Signed-off-by: John W.
