[PATCH 1/1] PCI: Add function 1 DMA alias quirk for Marvell 9120

[Sakari Ailus]

Marvell 9120 SATA controller has the same issue as a number of others, use
the same quirk for this one. The other quirks were added by patch
"PCI: Add function 1 DMA alias quirk for Marvell devices"
(commit id cc346a4714a59d08c118e8f33fd86692d3563133).

Hi,

I recently booted the v4.0.1 kernel with intel-iommu enabled and had similar
issues as in the original bug report with Marvell 88SE9120 (rev 12). The
same quirk appears to work for that one as well.

Applied to pci/virtualization for v4.2, thanks!

You can add my ack, but the linux-pci list is the proper list to get
this upstream.  I suggest resending it there.  Thanks,
