NAME
       device_for_each_child_reverse - device child iterator in reversed order.

SYNOPSIS
       int device_for_each_child_reverse(struct device * parent, void * data,
                                         int (*fn) (struct device *dev, void *data));

ARGUMENTS
       parent
           parent struct device.

       data
           data for the callback.

       fn
           function to be called for each device.

DESCRIPTION
       Iterate over parent's child devices, and call fn for each, passing it data.

       We check the return of fn each time. If it returns anything other than 0, we break out and
       return that value.
