From: Arnd Bergmann <arnd@xxxxxxxx> A couple of architectures build the __weak versions of pci_create_resource_files() and pci_remove_resource_files() but don't have prototypes for these, which causes warnings: drivers/pci/pci-sysfs.c:1253:12: error: no previous prototype for 'pci_create_resource_files' [-Werror=missing-prototypes] 1253 | int __weak pci_create_resource_files(struct pci_dev *dev) { return 0; } drivers/pci/pci-sysfs.c:1254:13: error: no previous prototype for 'pci_remove_resource_files' [-Werror=missing-prototypes] 1254 | void __weak pci_remove_resource_files(struct pci_dev *dev) { return; } Move the prototypes from alpha architecture into the global header to avoid these warnings for all of them.
