Date: Mon Sep 24 2018 - 08:12:58 EST

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


From: Raed Salem <raeds@xxxxxxxxxxxx>

[ Upstream commit c88a026e01219488e745f4f0267fd76c2bb68421 ]

The memory allocated for the slow path table flow group input structure
was not freed upon successful return, fix that.
