And what is wrong with this?

Also, 5.4 is really old for typec stuff, please use 5.7 at the latest.

Against Nvidia's driver recommendations, turns out I had i2c-nvidia-gpu module
enabled in kernel. The error went away by disabling this. As I don't have
proper hardware to test this (e.g. attached monitor to the USB type-C port), I
cannot provide any useful information.
