Subject: PCI: Add new ID for Intel GPU "spurious interrupt" quirk
commit 7c82126a94e69bbbac586f0249e7ef11e681246c upstream.
After a CPU upgrade while keeping the same mainboard, we faced "spurious
interrupt" problems again.
It turned out that the new CPU also featured a new GPU with a different PCI
ID.
Add this PCI ID to the quirk table. Probably all other Intel GPU PCI IDs
are affected, too, but I don't want to add them without a test system.
See f67fd55fa96f ("PCI: Add quirk for still enabled interrupts on Intel
Sandy Bridge GPUs") for some history.
