Subject: [PATCH 5.15.y 1/2] backlight: lm3630a_bl: Remove redundant 'flush_workqueue()' calls
Date: Tue, 3 Nov 2026 09:58:46 -0500 [thread overview]
Message-ID: <20261103145824.4109030-1-sashal@kernel.org> (raw)
In-Reply-To: <2026110358-afar-payable-c2d6@gregkh>
From: Xu Wang <vulab@iscas.ac.cn>
[ Upstream commit adc122011125682932ef279d717153670feedde4 ]
'destroy_workqueue()' already drains the queue before destroying it, so
there is no need to flush it explicitly.
Remove the redundant 'flush_workqueue()' calls.
