Subject: net/smc: no need to flush smcd_dev's event_wq before destroying it
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5e4a43ceb22a6fd2d372fde923a6a95ef6728fd7;p=linux.git

net/smc: no need to flush smcd_dev's event_wq before destroying it

destroy_workqueue() already calls drain_workqueue(), which is a stronger
variant of flush_workqueue().
