From 9493a6361d8155f500b1e7fed7ab5fb4fa437bfa Mon Sep 17 00:00:00 2001 From: Zhenzhong Duan Date: Thu, 12 Mar 2020 14:09:54 +0800 Subject: [PATCH] iommu/vt-d: Fix the wrong printing in RHSA parsing commit b0bb0c22c4db623f2e7b1a471596fbf1c22c6dc5 upstream. When base address in RHSA structure doesn't match base address in each DRHD structure, the base address in last DRHD is printed out. This doesn't make sense when there are multiple DRHD units, fix it by printing the buggy RHSA's base address.
