Detailed Description

class_find_device - device iterator for locating a particular device 're iterating : Device to begin with : data for the match function : function to check device

class_for_each_device - device iterator 're iterating : the device to start with in the list, if any.

Initialize class iterator such that it iterates over devices of

: data for the callback

This is similar to the class_for_each_dev() function above, but it returns a reference to a device that is 'found' for later use, as determined by the callback.

The callback should return 0 if the device doesn't 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.
