From d4e0984f12ea958e0f2def90ddb1e193a896932b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 16 Jun 2026 18:39:59 +0200 Subject: [PATCH] PCI: imx6: Fix building against PCI_HOST_COMMON When CONFIG_PCI_HOST_COMMON is set to =m, the i.MX6 PCIe driver fails to link. This can happen when only i.MX endpoint mode is enabled but not host mode, which would indirectly enable the host-common driver itself. ld.lld: error: undefined symbol: pci_host_common_parse_ports >>> referenced by pci-imx6.c >>> drivers/pci/controller/dwc/pci-imx6.o:(imx_pcie_host_init) in archive vmlinux.a ld.lld: error: undefined symbol: pci_host_common_delete_ports >>> referenced by pci-imx6.c >>> drivers/pci/controller/dwc/pci-imx6.o:(imx_pcie_host_init) in archive vmlinux.a >>> referenced by pci-imx6.c >>> drivers/pci/controller/dwc/pci-imx6.o:(imx_pcie_host_init) in archive vmlinux.a Select the common module from the endpoint support directly.
