10                                         void * data,
11                                         int (*fn) (struct input_handle *, void *));

ARGUMENTS

14       handler
15           input handler to iterate
16
17       data
18           data for the callback
19
20       fn
21           function to be called for each handle

DESCRIPTION

24       Iterate over bus's list of devices, and call fn for each, passing it
25       data and stop when fn returns a non-zero value. The function is using
26       RCU to traverse the list and therefore may be usind in atonic contexts.
27       The fn callback is invoked from RCU critical section and thus must not
28       sleep.
