4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Slaby jslaby@suse.cz
[ Upstream commit 4dc12ffeaeac939097a3f55c881d3dc3523dff0c ]
l2tp_tunnel_delete does not return anything since commit 62b982eeb458 ("l2tp: fix race condition in l2tp_tunnel_delete"). But call sites of l2tp_tunnel_delete still do casts to void to avoid unused return value warnings.
Kill these now useless casts.
