Subject: [PATCH 05/13] iommu/rockchip: Use dev_iommu_priv_get/set()
Date: Thu, 25 Jun 2020 15:08:28 +0200 [thread overview]
Message-ID: <20200625130836.1916-6-joro@8bytes.org> (raw)
In-Reply-To: <20200625130836.1916-1-joro@8bytes.org>
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.
Signed-off-by: Joerg Roedel <jroedel@suse.de>
