Subject: [PATCH] memblock: Add missing debug code to memblock_add_node()
Date:   Wed, 11 Aug 2021 10:54:36 +0200
Message-Id: <c45e5218b6fcf0e3aeb63d9a9d9792addae0bb7a.1628672041.git.geert+renesas@glider.be>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

All other memblock APIs built on top of memblock_add_range() contain
debug code to print their parameters.
