Subject: [PATCH RESEND v3 net-next 01/12] net: mscc: ocelot: rename ocelot_netdevice_port_event to ocelot_netdevice_changeupper

From: Vladimir Oltean <vladimir.oltean@....com>

ocelot_netdevice_port_event treats a single event, NETDEV_CHANGEUPPER.
So we can remove the check for the type of event, and rename the
function to be more suggestive, since there already is a function with a
very similar name of ocelot_netdevice_event.

Signed-off-by: Vladimir Oltean <vladimir.oltean@....com>
---
Changes in v3:
None.

Changes in v2:
Fixed build by removing the "event" argument of ocelot_netdevice_changeupper.
