- * pci_get_bus_and_slot - locate PCI device from a given PCI slot
+ * pci_get_bus_and_slot - locate PCI device from a given PCI bus & slot
  * @bus: number of PCI bus on which desired PCI device resides
  * @devfn: encodes number of PCI slot in which the desired PCI
  * device resides and the logical device number within that slot
  * in case of multi-function devices.
  *
+ * Note: the bus/slot search is limited to PCI domain (segment) 0.

  * Given a PCI bus and slot/function number, the desired PCI device
  * is located in system global list of PCI devices.  If the device
  * is found, a pointer to its data structure is returned.  If no
