NAME
       input_handler_for_each_handle - handle iterator

SYNOPSIS
       int input_handler_for_each_handle(struct input_handler * handler, void * data,
                                         int (*fn) (struct input_handle *, void *));

ARGUMENTS
       handler
           input handler to iterate

       data
           data for the callback

       fn
           function to be called for each handle

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