From 96aec911482246a319bf457f39fa848ce436c8fd Mon Sep 17 00:00:00 2001 From: "Lendacky, Thomas" Date: Wed, 14 Oct 2015 12:37:32 -0500 Subject: amd-xgbe: Use system workqueue for device restart A previous patch switched from using the system workqueue to the device workqueue for various operations. During a device restart the device workqueue is flushed so the restart cannot use this workqueue or else a deadlock results. Move the device restart back to using the system workqueue.
