[PATCH net] net: dsa: Bring back device detaching in dsa_slave_suspend()
From: Florian Fainelli
Date: Wed Jan 25 2017 - 12:10:56 EST
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")
