bus_find_device_by_name — device iterator for locating a particular device of a specific name
| struct device * bus_find_device_by_name ( | struct bus_type * bus, | 
| struct device * start, | |
| const char * name ); | 
   This is similar to the bus_find_device function above, but it handles
   searching by a name automatically, no need to write another strcmp matching
   function.
