+Subject: Revert "wifi: cfg80211: fix CQM for non-range use"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit 4a7e92551618f3737b305f62451353ee05662f57 which is
+commit 7e7efdda6adb385fbdfd6f819d76bc68c923c394 upstream.
+
+It needed to have commit 076fc8775daf ("wifi: cfg80211: remove wdev
+mutex") applied to properly work, otherwise regressions happen.
