driver_find_device - device iterator for locating a particular device.
struct device * driver_find_device (struct device_driver * drv,
struct device * start,
void * data,
int (*match) <funcparams>struct device *, void *</funcparams>);
drv The device’s driver
start Device to begin with
data Data to pass to match function
match Callback function to check device
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.
