| Subject: [PATCH] iommu/amd: Apply the same IVRS IOAPIC workaround to Acer |
| Aspire A315-41 |
| |
| commit ad3e8da2d422c63c13819a53d3c5ea9312cc0b9d upstream. |
| |
| Acer Aspire A315-41 requires the very same workaround as the existing |
| quirk for Dell Latitude 5495. Add the new entry for that. |
