From 5d2569cb4a65c373896ec0217febdf88739ed295 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Mon, 26 Sep 2022 09:33:50 -0500 Subject: thunderbolt: Explicitly enable lane adapter hotplug events at startup Software that has run before the USB4 CM in Linux runs may have disabled hotplug events for a given lane adapter. Other CMs such as that one distributed with Windows 11 will enable hotplug events. Do the same thing in the Linux CM which fixes hotplug events on "AMD Pink Sardine".
