I don't see the point of removing this, we've used it for the last 5
years to figure out when the probe complete vs. when the device becomes
attached. It's a simple log that helped us immensely with race
conditions, etc.

And no, sysfs is not a viable alternative to look at CI logs, and
enabling dynamic debug on the driver core would be way to verbose.
