From 60bbd9d411e32328dbecaff9ec5dfab29b546aba Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Beh=C3=BAn?= Date: Sat, 19 Sep 2020 20:03:01 +0200 Subject: [PATCH] leds: lm36274: use devres LED registering function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that the potential use-after-free issue is resolved we can use devres for LED registration in this driver. By using devres version of LED registering function we can remove the .remove method from this driver.
