class_find_device - device iterator for locating a particular device


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



the class we're iterating


data for the match function


function to check device


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 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, 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.

We hold class->sem in this function, so it can not be re-acquired in match, otherwise it will self-deadlocking. For example, calls to add or remove class members would be verboten.
