Subject: [PATCH net] net: dsa: Bring back device detaching in dsa_slave_suspend()
Date: Wed, 25 Jan 2017 09:10:41 -0800 [thread overview]
Message-ID: <20170125171041.21442-1-f.fainelli@gmail.com> (raw)
Commit 448b4482c671 ("net: dsa: Add lockdep class to tx queues to avoid
lockdep splat") removed the netif_device_detach() call done in
dsa_slave_suspend() which is necessary, and paired with a corresponding
netif_device_attach(), bring it back.
Fixes: 448b4482c671 ("net: dsa: Add lockdep class to tx queues to avoid lockdep splat")
