Andrzej Hajda f8cc091e05 drm/i915/fbdev: suspend HPD before fbdev unregistration 
HPD event after fbdev unregistration can cause registration of deferred
fbdev which will not be unregistered later, causing use-after-free.
To avoid it HPD handling should be suspended before fbdev unregistration.

It should fix following GPF:
