Good idea, thanks! They're called only from pci-acpi.c, so I moved
them inside the #ifdef CONFIG_ACPI above:
#ifdef CONFIG_ACPI
int pci_acpi_program_hp_params(struct pci_dev *dev);
...
#ifdef CONFIG_PCIE_DPC
void pci_acpi_add_edr_notifier(struct pci_dev *pdev);
void pci_acpi_remove_edr_notifier(struct pci_dev *pdev);
#endif
#else
static inline int pci_acpi_program_hp_params(struct pci_dev *dev)
{
return -ENODEV;
}
#ifdef CONFIG_PCIE_DPC
static inline void pci_acpi_add_edr_notifier(struct pci_dev *pdev) { }
static inline void pci_acpi_remove_edr_notifier(struct pci_dev *pdev) { }
#endif
#endif
