Subject: [PATCH 1/2] scsi: hisi_sas: Remove unnecessary devm_kfree
Date: Mon, 11 Jan 2021 23:32:01 +0100 [thread overview]
Message-ID: <20210111223202.26369-2-huobean@gmail.com> (raw)
In-Reply-To: <20210111223202.26369-1-huobean@gmail.com>
From: Bean Huo <beanhuo@micron.com>
The memory allocated with devm_kzalloc() is freed automatically
no need to explicitly call devm_kfree.
