led: core: Fix brightness setting when setting delay_off=0
With the current code, the following sequence won't work : echo timer > trigger echo 0 > delay_off * at this point we call ** led_delay_off_store ** led_blink_set *** stop timer ** led_blink_setup ** led_set_software_blink *** if !delay_on, led off *** if !delay_off, set led_set_brightness_nosleep <--- LED_BLINK_SW is set but timer is stop *** otherwise start timer/set LED_BLINK_SW flag echo xxx > brightness * led_set_brightness ** if LED_BLINK_SW *** if brightness=0, led off *** else apply brightness if next timer <--- timer is stop, and will never apply new setting ** otherwise set led_set_brightness_nosleep To fix that, when we delete the timer, we should clear LED_BLINK_SW.
