David Woodhouse d14053b3c7 iommu/vt-d: Fix ATSR handling for Root-Complex integrated endpoints ... The VT-d specification says that "Software must enable ATS on endpoint devices behind a Root Port only if the Root Port is reported as supporting ATS transactions." We walk up the tree to find a Root Port, but for integrated devices we don't find one — we get to the host bridge. In that case we *should* allow ATS. Currently we don't, which means that we are incorrectly failing to use ATS for the integrated graphics. Fix that. We should never break out of this loop "naturally" with bus==NULL, since we'll always find bridge==NULL in that case (and now return 1). So remove the check for (!bridge) after the loop, since it can never happen. If it did, it would be worthy of a BUG_ON(!bridge). But since it'll oops anyway in that case, that'll do just as well.
