Subject: [PATCH 05/13] iommu/rockchip: Use dev_iommu_priv_get/set()
Date:   Thu, 25 Jun 2020 15:08:28 +0200
Message-Id: <20200625130836.1916-6-joro@8bytes.org>
In-Reply-To: <20200625130836.1916-1-joro@8bytes.org>
References: <20200625130836.1916-1-joro@8bytes.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Joerg Roedel <jroedel@suse.de>

Remove the use of dev->archdata.iommu and use the private per-device
pointer provided by IOMMU core code instead.
