Maybe make this optional if someone wants to force autodetection over it it might be acceptable but doing that by default can also heat up devices. Also if it thinks it has detected something, after toggling some gpios the footprint might look different again after reloading it.. it's just a failed technique doing it that way... regards, Markus -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
