[PATCH 05/12] drm/i915: Suspend the framebuffer console during driver shutdown

[Imre Deak]

Suspend the FB console during driver shutdown the same way this is done
during system resume. This should prevent any HPD event to trigger a new
FB probe/modeset cycle happening in parallel with the display HW
disable/uninitialize steps.

A preceding FB HPD event handling may be still pending, resulting in a
probe/modeset like the above, these will be prevented by a later change
in this patchset.
