While before this patch the GPIO would be initialized in the disabled state, the call to backlight_update_status at the end of the probe function would still enable the backlight afterwards. regards Philipp -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
