I'm still not an expert in the DM internals. I fail to see, where
the actual probing is happening in the loop. Is it buried in the
uclass_first_device() call?
The probing is happening in both uclass_first_device() and 
uclass_next_device().
The uclass_first_device() will probe the first device.
While uclass_next_device() will probe the rest if they exist.
Best regards,
Thomas
