--- Comment #2 from Imre Deak <imre.deak at intel.com> ---
The error message is about a known issue in VBT about port D being incorrectly
marked there as a non-legacy TypeC port. Besides the driver noticing this and
correcting its own state tracking, this doens't cause any further problems.

It is still useful to emit an error level message about this to catch buggy
BIOSen in the wild where drm debugging is not enabled.

The BIOS/VBT team has been notified about the problem with an internal bug
ticket, we are waiting for them to fix VBT.

The error message is very specific (it's about the above exact issue on port
D), so based on there being no further implications, I suggests lowering the
priority of this ticket and setting a filter in cibug-log (I'm guessing it's
done already) until the VBT is fixed.
