Something like:

static inline void *snd_soc_widget_get_pdata(struct snd_soc_dapm_widget *w)
        return w->private_data;

static inline void snd_soc_widget_set_pdata(struct snd_soc_dapm_widget *w,
			void *data)
        w->private_data = data;

Another option at the moment is that I create global variable within the omap-
mcpdm.c, so I can have access to the mcpdm within the dapm event handler.
