Hi CI team,

could you please re-report this result?

The failure is unrelated, see the details below.

kbl doesn't have TypeC connectors, so the changes in the patchset are
unrelated to this failure.

The failure is:
<4> [163.791609] WARNING: CPU: 0 PID: 5768 at ./include/linux/sched.h:2185 __ww_mutex_wound+0xb9/0x160

and looks to be related to:
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/14804

tgl does have TypeC connectors, however nothing is connected on those,
so none of the TypeC changes in the patchset should have an effect
(they only matter if a sink got ever connected on a TypeC connector).

It looks to be the same ww_mutex() issue above.
