Subject: [PATCH 2/4] drm/vmwgfx: remove CONFIG_INTEL_IOMMU ifdefs
Date:   Sat,  5 Jan 2019 09:01:06 +0100
Message-Id: <20190105080108.14837-3-hch@lst.de>
In-Reply-To: <20190105080108.14837-1-hch@lst.de>
References: <20190105080108.14837-1-hch@lst.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

intel_iommu_enabled is defined as always false for !CONFIG_INTEL_IOMMU,
so remove the ifdefs around it.
