From 863d1a8d5523d345186277014cebe861f2782130 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Sat, 23 Mar 2019 19:45:13 +0100 Subject: [PATCH] net: dsa: mv88e6xxx: remove unneeded cmode initialization This partially reverts ed8fe20205ac ("net: dsa: mv88e6xxx: prevent interrupt storm caused by mv88e6390x_port_set_cmode"). I missed that chip->ports[].cmode is overwritten anyway by the cmode caching in mv88e6xxx_setup(). Signed-off-by: Heiner Kallweit Signed-off-by: David S.
