If I understood the platform core code correctly, the probe is always sync in
the case of platform drivers. Unless .probe_type = PROBE_PREFER_ASYNCHRONOUS is
set or a module is loaded using with the "async_probe=1" parameter. So I believe
the wait queue won't be needed. The only DRM driver that forces an async probe is
drivers/gpu/drm/hyperv/hyperv_drm_drv.c AFAICT.

So I would drop this patch from the set for now.
