[PATCH] media: mtk-vpu: Remove redundant 'flush_workqueue()' calls

From: Christophe JAILLET
Date: Thu Oct 14 2021 - 14:21:53 EST


'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);
