Subject: [PATCH 18/20] i40iw: Redefine i40iw_mmiowb() to do nothing
Date: Fri, 1 Mar 2019 14:03:46 +0000 [thread overview]
Message-ID: <20190301140348.25175-19-will.deacon@arm.com> (raw)
In-Reply-To: <20190301140348.25175-1-will.deacon@arm.com>
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.
