From 97ea1202601a7f936c9c9a86f900ec001cb589d3 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Thu, 25 Jun 2020 15:08:27 +0200 Subject: [PATCH] iommu/omap: Use dev_iommu_priv_get/set() Remove the use of dev->archdata.iommu and use the private per-device pointer provided by IOMMU core code instead.
