+Subject: Revert "thunderbolt: Hide authorized attribute if router does not support PCIe tunnels"
+
+From: Mika Westerberg <mika.westerberg@linux.intel.com>
+
+commit 8e3341257e3b5774ec8cd3ef1ba0c0d3fada322b upstream.
+
+This reverts commit 6f3badead6a078cf3c71f381f9d84ac922984a00.
+
+It turns out bolt depends on having authorized attribute visible under
+each device. Hiding it makes bolt crash as several people have reported
+on various bug trackers. For this reason revert the commit.
