DRIVER_FIND_DEVICE(9)					   Device drivers infrastructure				     DRIVER_FIND_DEVICE(9)

NAME
       driver_find_device - device iterator for locating a particular device.

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

ARGUMENTS
       drv
	   The device's driver

       start
	   Device to begin with

       data
	   Data to pass to match function

       match
	   Callback function to check device

DESCRIPTION
       This 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.
