From 672ddeffeb2afad18fe1a2fc5aa14a07b4da1551 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 18 Aug 2010 09:35:22 -0700 Subject: [PATCH] iwlwifi: do not spuriously call ieee80211_scan_completed When a scan is aborted because the corresponding virtual interface is removed, we may still later attempt to tell mac80211 that the scan completed. This is obviously wrong, since we already told it that it was aborted, so don't do that. Signed-off-by: Johannes Berg Signed-off-by: Wey-Yi Guy Signed-off-by: John W.
