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:
