Re: [PATCH] net: dsa: mv88e6xxx: fix netdev reference leak on remove

mv88e6xxx_probe() uses the referenced network device provided through
platform data, but the remove path does not drop the corresponding
reference.

The probe failure path correctly calls dev_put() for pdata->netdev.
However, after a successful probe, mv88e6xxx_remove() tears down the
switch resources without releasing this reference, leaving the network
device reference count unbalanced after driver removal.

Call dev_put() in mv88e6xxx_remove() after the switch resources have
been torn down.

dev_put() and dev_get() should be used in pairs. Where is the
dev_get()?
