device_find_child - device iterator for locating a particular device.
2. SYNOPSIS ▲
struct device * device_find_child(struct device * parent , void * data , int (* match ) (struct device *dev, void *data));
3. ARGUMENTS ▲
parent struct device
Data to pass to match function
Callback function to check device
4. DESCRIPTION ▲
This is similar to the device_for_each_child function above, but it returns a reference to a device that is AqfoundAq for later use, as determined by the match callback.
The callback should return 0 if the device doesnAqt 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.
