Subject: [PATCH 04/10] sh: move ioremap_fixed details out of <asm/io.h>
Date: Fri, 26 Jun 2020 10:07:11 +0200	[thread overview]
Message-ID: <20200626080717.1999041-5-hch@lst.de> (raw)
In-Reply-To: <20200626080717.1999041-1-hch@lst.de>

ioremap_fixed is an internal implementation detail and should not be
exposed to drivers.
