Man page 9 : bus_find_device_by_name

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 );

bus
    bus type

start
    Device to begin with

name
    name of the device to match

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.
