Regression on i915

[Borah, Chaitanya Kumar]

Hello Alexander,

We have two gitlab issues[1] where a phantom display is detected by the system (with i915 driver).
The following patch[2] has been identified as the first bad commit after bisect.

"b49420d6a1 video/aperture: optionally match the device in sysfb_disable()"

Could you please check why the patch causes this regression and provide a fix if necessary?

Regards

Chaitanya
