So we know that 0x104 doesn't need the fixup, so resumably only 0x101 needs the fixup? Regards, Bjorn

So we know that 0x104 doesn't need > the fixup, so presumably only 0x101 needs the fixup? I apologize for the tone of my reply. I did not mean to sound so snarky. All I can say is that, if I remember correctly, the fixup was not necessary on apq8098 (0x0105) and it was probably not required on msm8996 and sdm845. For older platforms, all bets are off. Regards.

We can drop the not-affected SoCs with follow-up patches once we are sure that we do not break the supported SoCs.

There exists non-bridge PCIe devices with PCI_VENDOR_ID_QCOM, so limit the fixup to only affect the relevant PCIe bridges.
