[PATCH] PCI: Add Wellsburg (X99) to Intel PCH root port ACS quirk

From: Alex Williamson
Date: Thu Jan 22 2015 - 13:15:49 EST


Intel has confirmed that the Wellsburg chipset, while not reporting
ACS, does provide the proper isolation through the RCBA/BSPR
registers, so the same quirk works for this set of device IDs.
