[PATCH 4.19 175/195] net: dsa: b53: Always use dev->vlan_enabled in b53_configure_vlan()

[Greg Kroah-Hartman]

From: Florian Fainelli <f.fainelli@xxxxxxxxx>

[ Upstream commit df373702bc0f8f2d83980ea441e71639fc1efcf8 ]

b53_configure_vlan() is called by the bcm_sf2 driver upon setup and
indirectly through resume as well. During the initial setup, we are
guaranteed that dev->vlan_enabled is false, so there is no change in
behavior, however during suspend, we may have enabled VLANs before, so we
do want to restore that setting.

Fixes: dad8d7c6452b ("net: dsa: b53: Properly account for VLAN filtering")
Fixes: 967dd82ffc52 ("net: dsa: b53: Add support for Broadcom RoboSwitch")
