 Steps to reproduce:
 1) echo timer > /sys/class/leds/gta02-aux:red/trigger
 2) echo 300 > /sys/class/leds/gta02-aux:red/delay_on
 3) echo 700 > /sys/class/leds/gta02-aux:red/delay_off
 4) echo 0 > /sys/class/leds/gta02-aux:red/brightness
 5) cat /sys/class/leds/gta02-aux:red/trigger

 Expected results:
 5) LED is OFF and trigger is none since Documentation/leds-class.txt says

 "You can change the brightness value of a LED independently of the timer
 trigger. However, if you set the brightness value to LED_OFF it will also
 disable the timer trigger."

 Actual results:
 5) LED keeps blinking and trigger is still timer:

 none rfkill0 nand-disk rfkill1 mmc0 adapter-online usb-online ac-online
 battery-charging-or-full battery-charging battery-full [timer] netdev
 backlight mmc1
