Subject: [PATCH 04/20] ARM/io: Remove useless definition of mmiowb()
Date:   Fri,  1 Mar 2019 14:03:32 +0000
Message-Id: <20190301140348.25175-5-will.deacon@arm.com>
In-Reply-To: <20190301140348.25175-1-will.deacon@arm.com>
References: <20190301140348.25175-1-will.deacon@arm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

ARM includes asm-generic/io.h, which provides a dummy definition of
mmiowb() if one isn't already provided by the architecture.

Remove the useless definition.
