Subject: net: dsa: Bring back device detaching in dsa_slave_suspend()
From: Florian Fainelli <f.fainelli@xxxxxxxxx>
[ Upstream commit f154be241d22298d2b63c9b613f619fa1086ea75 ]
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.
