Subject: [PATCH net-next v3 4/4] leds: trig-netdev: Disable offload on deactivation of trigger
Date: Tue, 8 Aug 2023 23:04:36 +0200 [thread overview]
Message-ID: <20230808210436.838995-5-andrew@lunn.ch> (raw)
In-Reply-To: <20230808210436.838995-1-andrew@lunn.ch>
Ensure that the offloading of blinking is stopped when the trigger is
deactivated. Calling led_set_brightness() is documented as stopping
offload and setting the LED to a constant brightness.
