NAMEdriver_find_device − device iterator for locating a particular device​.

---

SYNOPSISstruct device * driver_find_device(struct device_driver * drv, struct device * start, void * data, int (*match) (struct device *dev, void *data));

---

ARGUMENTSdrv The device´s driver start Device to begin with data Data to pass to match function match Callback function to check device

---

DESCRIPTIONThis is similar to the driver_for_each_device function above, but it returns a reference to a device that is ´found´ for later use, as determined by the match callback​. The callback should return 0 if the device doesn´t match and non−zero if it does​. If the callback returns non−zero, this function will return to the caller and not iterate over any more devices​.
