If the previous can_net device has been successfully allocated, its

Your analysis is correct, the netdev_priv() will never fail. But how
will this trigger a mem leak on alloc_candev()? I've removed that
statement. I'll add it back, if I've missed something.

Applied to linux-can-next/testing.

Thanks,
