1. NAME

class_find_device - device iterator for locating a particular device

2. SYNOPSIS

struct device * class_find_device(struct class *  class , struct device *  start , const void *  data , int (* match ) (struct device *, const void *));

3. ARGUMENTS

class
    the class weAqre iterating

start
    Device to begin with

data
    data for the match function

match
    function to check device

4. DESCRIPTION

This is similar to the class_for_each_dev 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, this function will return to the caller and not iterate over any more devices.

Note, you will need to drop the reference with put_device after use.

fn is allowed to do anything including calling back into class code. ThereAqs no locking restriction.
