Subject: [PATCH 13/21] m68k: rename __iounmap and mark it static
Date: Thu, 17 Oct 2019 19:45:46 +0200 [thread overview]
Message-ID: <20191017174554.29840-14-hch@lst.de> (raw)
In-Reply-To: <20191017174554.29840-1-hch@lst.de>
m68k uses __iounmap as the name for an internal helper that is only
used for some CPU types. Mark it static and give it a better name.
Signed-off-by: Christoph Hellwig <hch@lst.de>
