From 2d72289095e9621158acf1d59a830cfe920fa93b Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 23 Apr 2009 10:38:26 +0200 Subject: mac80211: internally clear failed scans properly When the IBSS code wants to scan, but that fails, we can get stuck in a situation where you can never scan again. Fix this by properly notifying ourselves when the scan request has failed. Signed-off-by: Johannes Berg Signed-off-by: John W.
