6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brett Creeley <brett.creeley@xxxxxxx>
[ Upstream commit 9590d32e090ea2751e131ae5273859ca22f5ac14 ]
If register_netdev() fails, then the driver leaks the netdev notifier.
Fix this by calling ionic_lif_unregister() on register_netdev()
failure. This will also call ionic_lif_unregister_phc() if it has
already been registered.
Fixes: 30b87ab4c0b3 ("ionic: remove lif list concept")
