That seems to be the problem. fw_devlink appears to think probe is an atomic operation. A device is not probed, or full probed. Where as the drivers are making use of it being non atomic. Maybe fw_devlink needs the third state, probing. And when deciding if a device can be probed and depends on a device which is currently probing, it looks deeper, follows the phandle and see if the resource is actually available? Andrew
