Yes, the heartbeat trigger driver assumes brightness_set() routine can be called from timer. Other led-triggers also have this assumption. So I'd suggest using workqueue for your led driver, as like as the leds-gpio driver. Or you can just use the leds-gpio driver and implement the gpio interface (gpio_set_value_cansleep) instead of the led interface. --- Atsushi Nemoto -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
