From adab0b07cbbc73f9fc338e4fc1749714dd093a7c Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Mon, 19 Aug 2019 15:22:48 +0200 Subject: [PATCH] iommu: Use Functions to set default domain type in iommu_set_def_domain_type() There are functions now to set the default domain type which take care of updating other necessary state. Don't open-code it in iommu_set_def_domain_type() and use those functions instead.
