Re-checked the error. This is a -ENOMEM. So normally we could ignore it.
But on the other hand, although we could find out the slave iface's
master in netdev_master_upper_dev_link(). It already go much further
and allocate some resource and change iface state. e.g.
[54273.968516] br0: port 1(em1) entered blocking state
[54273.973979] br0: port 1(em1) entered disabled state
So I think we'd better return as early as possible. I will post a fix
for this.
Thanks

If I'm not mistaken the bridge allocated resources for the port are
cleaned on kobject_init_and_add() error return. Or are you talking
about some other resources ?
Ah, my bad - you weren't talking about resource freeing.
Nevermind my comment.
