From 384e4bf0def9092b8c30f025c6b29982e2e96c50 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 25 Jan 2017 09:10:41 -0800 Subject: net: dsa: Bring back device detaching in dsa_slave_suspend() [ 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.
