[PATCH 3.12 022/116] pppoe: fix reference counting in PPPoE proxy

[Jiri Slaby]

From: Guillaume Nault <g.na...@alphalink.fr>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

[ Upstream commit 29e73269aa4d36f92b35610c25f8b01c789b0dc8 ]

Drop reference on the relay_po socket when __pppoe_xmit() succeeds.
This is already handled correctly in the error path.
