The\nsecond one is stored in port->netdev and later used by the remove path\nfor unregister_hdlc_device() and free_netdev().\n\nThis means that the registered netdev is not the same object that is\nunregistered and freed on remove. It also leaks the first allocation if\nthe second alloc_hdlcdev() call fails, and the first allocation is not\nchecked before ndev is used.\n\nOlder code allocated the HDLC netdev only once and stored the same object\nin both the local variable and port->netdev. The buggy conversion split\nthis into two alloc_hdlcdev() calls. A later rename changed the local\nvariable name to ndev, but the underlying mismatch remained.\n\nFix this by allocating the HDLC netdev only once and assigning the same\nobject to port->netdev."
