Description

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: [ 91.227923] PM: suspend entry (s2idle) [ 91.254598] Filesystems sync: 0.025 seconds [ 91.270518] Freezing user space processes [ 91.272266] Freezing user space processes completed (elapsed 0.001 seconds) [ 91.272686] OOM killer disabled.
