From b9c56ccb436d1e952bb1fc0ddf752669a116b310 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 10 Oct 2021 09:01:32 +0200 Subject: ethernet: Remove redundant 'flush_workqueue()' calls 'destroy_workqueue()' already drains the queue before destroying it, so there is no need to flush it explicitly. Remove the redundant 'flush_workqueue()' calls.
