Subject: [PATCH 2/2] ACPI: IORT: Add comments for not calling acpi_put_table()
Date: Fri, 8 May 2020 12:05:53 +0800	[thread overview]
Message-ID: <1588910753-18543-2-git-send-email-guohanjun@huawei.com> (raw)
In-Reply-To: <1588910753-18543-1-git-send-email-guohanjun@huawei.com>

The iort_table will be used at runtime after acpi_iort_init(),
so add some comments to clarify this to make it less confusing.
