Subject: [PATCH 4.20 19/76] net: dsa: mv88e6xxx: add call to mv88e6xxx_ports_cmode_init to probe for new DSA framework

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

------------------

From: Heiner Kallweit <hkallweit1@...il.com>

[ Upstream commit 3acca1dd17060332cfab15693733cdaf9fba1c90 ]

In the original patch I missed to add mv88e6xxx_ports_cmode_init()
to the second probe function, the one for the new DSA framework.

Fixes: ed8fe20205ac ("net: dsa: mv88e6xxx: prevent interrupt storm caused by mv88e6390x_port_set_cmode")
