This happened because it was under #ifdef CONFIG_PCIE_IPROC_PLATFORM: PCIE_IPROC_PLATFORM=y causes CONFIG_PCIE_IPROC_PLATFORM to be defined, but PCIE_IPROC_PLATFORM=m causes CONFIG_PCIE_IPROC_PLATFORM_MODULE to be defined. Move quirk_paxc_bridge() to pcie-iproc.c and drop the #ifdef so the quirk is always applied, whether iproc is built-in or a module. [bhelgaas: commit log, move to pcie-iproc.c, not pcie-iproc-platform.c] Link: https://lore.kernel.org/r/20191211174511.89713-1-wei.liu@kernel.org Signed-off-by: Wei Liu Signed-off-by: Bjorn Helgaas Signed-off-by: Sasha Levin --- drivers/pci/controller/pcie-iproc.c | 24 ++++++++++++++++++++++++ drivers/pci/quirks.c | 26 -------------------------- 2 files changed, 24 insertions(+), 26 deletions(-) diff --git a/drivers/pci/controller/pcie-iproc.c b/drivers/pci/controller/pcie-iproc.c index 9d5cbc75d5ae0..ec86414216f97 100644 --- a/drivers/pci/controller/pcie-iproc.c +++ b/drivers/pci/controller/pcie-iproc.c @@ -1526,6 +1526,30 @@ DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0xd802, DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0xd804, quirk_paxc_disable_msi_parsing); +static void quirk_paxc_bridge(struct pci_dev *pdev) +{ + /* + * The PCI config space is shared with the PAXC root port and the first + * Ethernet device.
