    s390/qdio: simplify debugfs code · d5d006fa
    Julian Wiedmann authored
    There's no need for error handling, the debugfs core is smart enough to
    deal with IS_ERR() internally.
    
    This will also keep us from creating the debugfs files if the device
    directory doesn't exist. Currently (because irq_ptr->debugfs_dev gets set
    to NULL on error) the files would be placed into the debugfs root - without
    any association to their parent device.
    
    On teardown, use the debugfs_remove_recursive() helper to avoid keeping
    track of each created file/directory.
