ipheth_carrier_set() is called from two locations. In ipheth_carrier_check_work(), its parameter 'dev' is set with container_of(work, ...) and can not be NULL. In ipheth_open(), dev is extracted from netdev_priv(net) and dereferenced before the call to ipheth_carrier_set(). The NULL pointer check of dev in ipheth_carrier_set() is therefore unnecessary and can be removed. Cc: Gustavo A. R.
