From cb93821a9eaf53fb60addd689d3fa9f106790be1 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Thu, 27 Oct 2011 18:47:46 +0300 Subject: [PATCH] ath6kl: don't use cfg80211_scan_request after cfg80211_scan_done() Use of cfg80211_scan_request is not valid after calling cfg80211_scan_done() but ath6kl_cfg80211_scan_complete_event() was doing exactly that. Change the function to call cfg80211_scan_done() last. This was found during code review, I didn't see any visible problems due to this bug.
