The sole non-static function in err.c, pcie_do_recovery(), is only called from: * aer.c (if CONFIG_PCIEAER=y) * dpc.c (if CONFIG_PCIE_DPC=y, which depends on CONFIG_PCIEAER) * edr.c (if CONFIG_PCIE_EDR=y, which depends on CONFIG_PCIE_DPC) Thus, err.c need not be compiled if CONFIG_PCIEAER=n. Also, pci_uevent_ers() and pcie_clear_device_status(), which are called from err.c, can be #ifdef'ed away unless CONFIG_PCIEAER=y. Since x86_64_defconfig doesn't enable CONFIG_PCIEAER, this change may slightly reduce compile time for anyone doing a test build with that config.
