Subject: [PATCH v2] PCI: qcom: Fix the fixup of PCI_VENDOR_ID_QCOM
Date: Thu, 26 Dec 2019 17:27:17 -0800
Message-ID: <20191227012717.78965-1-bjorn.andersson@linaro.org> (raw)

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

Stan, I picked up all the suggested device id's from the previous thread and
added 0x1000 for QCS404. I looked at creating platform specific defines in
pci_ids.h, but SDM845 has both 106 and 107... Please let me know if you would
prefer that I do this anyway.
