Subject: [PATCH 4.19 109/125] iommu/amd: Apply the same IVRS IOAPIC workaround to Acer Aspire A315-41

From: Takashi Iwai <tiwai@...e.de>

[ Upstream commit ad3e8da2d422c63c13819a53d3c5ea9312cc0b9d ]

Acer Aspire A315-41 requires the very same workaround as the existing
quirk for Dell Latitude 5495.  Add the new entry for that.
