Subject: [PATCH leds v2 36/50] leds: ns2: use devres LED registering function
Date: Fri, 18 Sep 2020 00:33:24 +0200 [thread overview]
Message-ID: <20200917223338.14164-37-marek.behun@nic.cz> (raw)
In-Reply-To: <20200917223338.14164-1-marek.behun@nic.cz>
By using devres version of LED registering function we can remove the
.remove method from this driver. The probe method also gets simpler.
