Hi,
I think there is a real bug to fix in 17.08-rc2.
More details below. Proposals are welcome.

After another look, there is something wrong here.
You are checking a probe policy (wrongly named scan_mode), in a function
which can be not related at all with bus probing.
Example with failsafe:
1/ We blacklist a device for the global EAL probe.
So the probing mode is set from "undefined" to "blacklist".
2/ We add the device as a failsafe slave.
3/ The device must be plugged, no matter of the probe policy.
But it is seen as a whitelist and rejected because the bus probing
is in blacklist mode.
I think it is a serious bug.
PS: thanks Matan for having checked it
