caif-hsi: fix possible deadlock in cfhsi_exit_module()
cfhsi_exit_module() calls unregister_netdev() under rtnl_lock(). but unregister_netdev() internally calls rtnl_lock(). So deadlock would occur. Fixes: c41254006377 ("caif-hsi: Add rtnl support") Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
