Unless the msm8998 /is/ affected, > and dw_pcie_setup_rc() actually fixes it? I think you hit the nail on the head... If I comment out //dw_pcie_wr_own_conf(pp, PCI_CLASS_DEVICE, 2, PCI_CLASS_BRIDGE_PCI); from dw_pcie_setup_rc() then pci_class() returns 0xff000000 instead of 0x6040000 So perhaps you're right: the quirk can be omitted altogether. Unless it is not possible to program the device class on older chips? Regards.
