Hi Armin,
As per the documentation, The automatic cleanup is only
triggered if the supplier probes or unbinds
Similarly, when the device link is added from supplier's ``->probe`` callback,
``DL_FLAG_AUTOREMOVE_SUPPLIER`` causes the device link to be automatically
purged when the supplier fails to probe or later unbinds.
To my understanding, the cleanup won't activate
here because we don't unbind pdev nor does the
probe fail.
Best regards,
yahia
