[pulseaudio-discuss] Are "_ref" and "_unref" not necessarily called in pairs?

For example, in file "module-suspend-on-idle.c ", why does the slot function "sink_input_state_changed_hook_cb" only reference the sink input but never unreference it?
So the reference count of the sink input will only increase? Does it matter?

Here is the code:
static pa_hook_result_t sink_input_state_changed_hook_cb(pa_core *c, pa_sink_input *s, struct userdata *u) {
    struct device_info *d;
    pa_sink_input_state_t state;

    pa_sink_input_assert_ref(s);  ... the sink input is referenced here. But where pa_sink_input_unref(s) is called?

    state = pa_sink_input_get_state(s);
    if (state == PA_SINK_INPUT_RUNNING || state == PA_SINK_INPUT_DRAINED)
        if ((d = pa_hashmap_get(u->device_infos, s->sink)))

    return PA_HOOK_OK;
