in some cases, this function can be called with a NULL jack argument.
See other codec drivers, e.g.

int arizona_jack_set_jack(struct snd_soc_component *component,
			  struct snd_soc_jack *jack, void *data)
{
	struct arizona_priv *info = snd_soc_component_get_drvdata(component);

	if (jack)
		return arizona_jack_enable_jack_detect(info, jack);
	else
		return arizona_jack_disable_jack_detect(info);
}
