Regression in 6.2.10 monitors connected via MST hub stay black

I found a regression while updating from 6.2.9 to 6.2.10 (Arch Linux). After upgrading to 6.2.10, my external monitors stopped working (no input) when starting my display manager. My hardware: Lenovo T14s AMD gen 1 Lenovo USB-C Dock Gen 2 40AS (firmware up to date: 13.24) 2 monitors connected via dock and thus via an MST hub

Reverting commit d7b5638bd3374a47f0b038449118b12d8d6e391c fixes the issue.

Best regards, Veronika
