Subject: [PATCH] batman-adv: Remove redundant 'flush_workqueue()' calls
Date: Mon, 10 Jan 2022 22:32:27 +0100	[thread overview]
Message-ID: <2c2454cd728f427cada2c24cdb1ef2609dec5efc.1641850318.git.christophe.jaillet@wanadoo.fr> (raw)

'destroy_workqueue()' already drains the queue before destroying it, so
there is no need to flush it explicitly.

Remove the redundant 'flush_workqueue()' calls.

This was generated with coccinelle:

expression E;
@@
- 	flush_workqueue(E);
	destroy_workqueue(E);
