device_find_child

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.
