From 50682409e225de4bbd1558be328460166b6955e2 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Tue, 27 Jul 2021 17:25:01 +0300 Subject: [PATCH] Revert "thunderbolt: Hide authorized attribute if router does not support PCIe tunnels" This reverts commit 2089e1b2f490018e3ac32904123dceb754a24faf. 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.
