## Description

In the Linux kernel, the following vulnerability has been resolved:  net: bridge: vlan: fix bugs caused by switchdev deletion errors  Allowing switchdev to prevent vlan deletion and error out in __vlan_del could cause multiple different issues - inconsistent state, memory leaks when flushing, NULL pointer dereference on bridge error when flushing. It doesn't make sense to allow it to stop __vlan_del, so log the error and continue with software vlan deletion. This is also consistent with 8021q behaviour.
