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 ▲
the class weAqre iterating
Device to begin with
data for the match function
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.
