Hello: This series was applied to netdev/net-next.git (master) by David S.

As discussed here: https://patchwork.kernel.org/project/netdevbpf/patch/20220214233111.1586715-2-vladimir.oltean@nxp.com/#24738869 no switchdev driver makes use of VLAN port objects that lack the BRIDGE_VLAN_INFO_BRENTRY flag. Notifying them in the first place rather seems like an omission of commit 9c86ce2c1ae3 ("net: bridge: Notify about bridge VLANs"). Since commit 3116ad0696dd ("net: bridge: vlan: don't notify to switchdev master VLANs without BRENTRY flag") that was just merged, the bridge no longer notifies switchdev upon creation of these VLANs, so we can remove the checks from drivers.
