Jack state is already exposed via the input layer by the ALSA jack core. Reporting of GPIO state via gpio_export() would be additional to that and would be purely for debug purposes, it would not be recommended for use by userspace applications. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
