Subject[PATCH 4.2.y-ckt 248/273] pppoe: fix reference counting in PPPoE proxy
Date
4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

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

[ Upstream commit 29e73269aa4d36f92b35610c25f8b01c789b0dc8 ]

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