Subject: [PATCH] ACPI: IORT: Add extra message "applying workaround" for off-by-1 issue
Date: Thu, 7 May 2020 21:41:08 +0800	[thread overview]
Message-ID: <1588858868-18039-1-git-send-email-guohanjun@huawei.com> (raw)

As we already applied a workaround for the off-by-1 issue,
it's good to add extra message "applying workaround" to
make people less uneasy to see such message in the boot log.
