| 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. |
