From 053596d9e26c86352c4b2b372f43f2746b97de45 Mon Sep 17 00:00:00 2001 From: Andreas Noever Date: Tue, 3 Jun 2014 22:04:06 +0200 Subject: thunderbolt: Handle hotplug events We receive a plug event callback whenever a thunderbolt device is added or removed. This patch fills in the tb_handle_hotplug method and starts reacting to these events by adding/removing switches from the hierarchy.
