Title:
Kernel bug when unplugging Thunderbolt 3 cable, leaves xHCI host
controller dead
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Bionic:
Fix Released
Status in linux source package in Cosmic:
In Progress
Bug description:
===SRU Justification===
[Impact]
When unplugging the Thunderbolt 3 cable from the TBT controller, kernel
oops.
[Test]
The user confirms this patch works.
[Fix]
tty_unregister_driver may be called more than 1 time in some
hotplug cases,it will cause the kernel oops. This patch checked
dbc_tty_driver to make sure it is unregistered only 1 time.
[Regression Potential]
Low. The change is to guard against null pointer, so it's the correct
behavior.
