When CONFIG_PCI is disabled, we still provide a pci_get_bus_and_slot() function that always returns NULL, but do not provide the same helper for pci_get_domain_bus_and_slot(): Replacing pci_get_bus_and_slot with pci_get_domain_bus_and_slot now causes a build error because of that: drivers/hwmon/coretemp.c: In function 'adjust_tjmax': drivers/hwmon/coretemp.c:250:32: error: implicit declaration of function 'pci_get_domain_bus_and_slot'; did you mean 'pci_get_bus_and_slot'? [-Werror=implicit-function-declaration] struct pci_dev *host_bridge = pci_get_domain_bus_and_slot(0, 0, devfn); This adds the missing helper function.
