Greetings,
Reverting the fingered commit below brought my GTX980 back to life.
41ab92d35ccd2d66bfb049bd34cd95f0304b0240 is the first bad commit
commit 41ab92d35ccd2d66bfb049bd34cd95f0304b0240
Author: Ville Syrjälä <ville.syrjala@linux.intel.com>
Date: Tue Jul 1 12:07:22 2025 +0300
drm: Make passing of format info to drm_helper_mode_fill_fb_struct() mandatory
Now that everyone passes along the format info to
drm_helper_mode_fill_fb_struct() we can make this behaviour
mandatory and drop the extra lookup.

See the patch Imre posted a few days ago:
https://lore.kernel.org/all/20250728101603.243788-3-imre.deak@intel.com
And the near-identical version I sent out yesterday before he pointed me
at the above :-)
Thanks,
