Change the pci_dev_present() stub which is used when CONFIG_PCI is not set from a #define to a static inline stub. Thix should fix clang -Werror builds failing due to errors like this: drivers/platform/x86/thinkpad_acpi.c:4475:35: error: unused variable 'fwbug_cards_ids' [-Werror,-Wunused-const-variable] Where fwbug_cards_ids is an array if pci_device_id-s passed to pci_dev_present() during a quirk check. Fixing this in include/linux/pci.h should ensure that the same issue is also fixed in any other drivers hitting the same -Werror issue.
