From d5926d9d6a183d109060f68c0b96ea2b33c15377 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 13 Sep 2010 14:46:34 +0200 Subject: [PATCH] iwlwifi: move scan completed flags handling Move the scan completed flags handling so that we can notify mac80211 about aborted scans with the correct status. Also queue the scan_completed work before the BT status update so that it won't see the bits still set (unless a new scan was started in which case that's fine.)
