My test driver calls netif_carrier_off before register_netdev and works
well,
without "netif_stop_queue() cannot be called before register_netdev()"
message.
Also, there are drivers that call netif_tx_stop_queue directly
and possible error message (with a reference to netif_stop_queue) will
be wrong.
Look at these commits:
e6484930d7c73d324bccda7d43d131088da697b9
18543a643fae694982c7d89c22436885f3506497
ed9af2e839c06c18f721da2c768fbb444c4a10e5
After the third commit, the second one became unnecessary.
Thus, I suggest either to remove the misleading message, or to replace
it with this:
pr_info("netif_tx_stop_queue(): dev_queue is null()\n");
