The device managed resources are freed when the device is detached, so it has to be bound in the first place.

Let's create a fake driver that we will bind to our fake device to benefit from the device managed cleanups in our tests.

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.
