Subject: [PATCH 5/5] acpi/processor: Make the acpi_duplicate_processor_id() static
Date:   Tue, 20 Mar 2018 19:04:32 +0800
Message-ID: <20180320110432.28127-6-douly.fnst@cn.fujitsu.com>
In-Reply-To: <20180320110432.28127-1-douly.fnst@cn.fujitsu.com>

Precedence: bulk

The acpi_duplicate_processor_id() is only called in acpi_processor_get_info(),
So move it in front of acpi_processor_get_info() and make it static.
