Hi,
6.3-rc6 alone fails the same way.
When the commit is added, it works.

And if 6.3-rc6 fails the same way, please one more check with 6.3-rc6 + this commit:

Hi,
Can you by chance cross reference 6.3-rc6?
It's quite possible we're missing some other commits to backport at the same
time.
Thanks,

Subject: 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
