[Nouveau] Some monitors not working after 6.2 kernel due to Nouveau commit

[stratus]

Dear Nouveau developers,
I encountered this problem using Artix Linux:
https://forum.artixlinux.org/index.php/topic,5859

On 2 laptops (Dell M4400 and M4500, Nvidia graphics using Nouveau) which have a VGA port, a Maxim MX11-LCD15 TV with a VGA port stopped working, also another Panasonic TX-26LXD500 TV using VGA. These are older TV's, from the 2000's, I guess the EDID might not be entirely compliant with modern standards. A newish AEC monitor (not TV) did work with the latest kernels so not all VGA connected monitors are affected.

From searching online it seems that there are numerous reports of monitors stopping working with the 6.2 kernel in various distros.

This is the commit where the problem apparently first appears:
