Subject: [PATCH net] staging: fsl-dpaa2: ethsw: Add missing netdevice check
Date: Fri, 22 Feb 2019 14:02:14 -0800 [thread overview]
Message-ID: <20190222220214.25401-1-f.fainelli@gmail.com> (raw)
port_switchdev_event() does not check that the target network device is
actually backed by the ethsw driver, this could be problematic in a
stacked environment case.
Fixes: 44baaa43d7cc ("staging: fsl-dpaa2/ethsw: Add Freescale DPAA2 Ethernet Switch driver")
