From 1d9619d5337df6cf56eb66b6c8213d1317583513 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 25 Apr 2016 23:11:22 +0100 Subject: [PATCH] net: dsa: mv88e6xxx: fix uninitialized error return The error return err is not initialized and there is a possibility that err is not assigned causing mv88e6xxx_port_bridge_join to return a garbage error return status. Fix this by initializing err to 0. Signed-off-by: Colin Ian King Reviewed-by: Vivien Didelot Signed-off-by: David S.
