Subject: [RFC PATCH 08/20] m68k: io: Remove useless definition of mmiowb()
Date:   Fri, 22 Feb 2019 18:50:14 +0000

X-Mailing-List: linux-kernel@vger.kernel.org

m68k 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.
