drm/i915: restore only the mode of this driver on lastclose (v2)
i915 calls the panic handler function on last close to reset the modes, however this is a really bad idea for multi-gpu machines, esp shareable gpus machines. So add a new entry point for the driver to just restore its own fbcon mode. v2: move code into fb helper, fix panic code to block mode change on powered off GPUs. [airlied: this hits drm core and I wrote it and it was reviewed on intel-gfx so really I signed it off twice ;-).] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Dave Airlie <airlied@redhat.com>
