device_find_child(9)
NAME
device_find_child - device iterator for locating a particular device.
SYNOPSIS
struct device * device_find_child(struct device * parent, void * data,
int (*match) (struct device *dev, void *data));
ARGUMENTS
- parent
- parent struct device
- data
- Data to pass to match function
- match
- Callback function to check device
DESCRIPTION
This is similar to the device_for_each_child 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 and a reference to the
current device can be obtained, this function will return to the caller
and not iterate over any more devices.
