Subject: [PATCH 4.9 32/51] net: dsa: Bring back device detaching in dsa_slave_suspend()
4.9-stable review patch. If anyone has any objections, please let me know.

From: Florian Fainelli <f.fainelli@...il.com>
[ 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.
Fixes: 448b4482c671 ("net: dsa: Add lockdep class to tx queues to avoid lockdep splat")
