Subject: [PATCH 18/20] i40iw: Redefine i40iw_mmiowb() to do nothing
Date:   Fri,  1 Mar 2019 14:03:46 +0000
Message-Id: <20190301140348.25175-19-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

mmiowb() is now implicit in spin_unlock(), so there's no reason to call
it from driver code. Redefine i40iw_mmiowb() to do nothing instead.
