CVE-2023-53678

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

drm/i915: Fix system suspend without fbdev being initialized

If fbdev is not initialized for some reason - in practice on platforms without display - suspending fbdev should be skipped during system suspend, fix this up. While at it add an assert that suspending fbdev only happens with the display present.

This fixes the following:

v2: CC stable. (Jani)
