Subject[PATCH 4.14 003/165] net/sched: fix refcnt leak in the error path of tcf_vlan_init()
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Davide Caratti <dcaratti@redhat.com>

[ Upstream commit 5a4931ae0193f8a4a97e8260fd0df1d705d83299 ]

Similarly to what was done with commit a52956dfc503 ("net sched actions:
fix refcnt leak in skbmod"), fix the error path of tcf_vlan_init() to avoid
refcnt leaks when wrong value of TCA_VLAN_PUSH_VLAN_PROTOCOL is given.

Fixes: 5026c9b1bafc ("net sched: vlan action fix late binding")
