I don't have time to look into this right now, so only reporting to
Abel.

Looks like there are two more warnings earlier on boot which appear to
be related:

[   10.730571] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: invalid connector number, ignoring
[   10.730656] pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: invalid connector number, ignoring
