From: Tejun Heo <tj@xxxxxxxxxx>
3.4.107-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit 2b21ef0aae65f22f5ba86b13c4588f6f0c2dbefb upstream.
Just like 0x1600 which got blacklisted by 66a7cbc303f4 ("ahci: disable
MSI instead of NCQ on Samsung pci-e SSDs on macbooks"), 0xa800 chokes
on NCQ commands if MSI is enabled. Disable MSI.
