--- Comment #4 from Heikki Krogerus (heikki.krogerus@xxxxxxxxxxxxxxx) ---
The NULL pointer is coming from UCSI driver, and it should not have any effect
on audio. UCSI is a firmware interface that we use just for reading the status
of the USB Type-C connectors. The firmware does all the actual negotiation with
the partner device, so the Dock in this case. Which dock is it?

I'll see if I can reproduce the NULL pointer dereference, but you can just
disable the UCSI drivers in your kernel configuration to get rid of it. Any
issues with the audio should not be related to it.
