   4 Subject: [PATCH 4/4] leds: trig-netdev: Disable offload on deactivation of
   5  trigger
   6
   7 Ensure that the offloading of blinking is stopped when the trigger is
   8 deactivated. Calling led_set_brightness() is documented as stopping
   9 offload and setting the LED to a constant brightness.
