From 7a43ccf85dfe06eef483c034e68b81ff326741aa Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 27 Mar 2026 11:27:29 +0100 Subject: [PATCH] leds: class: Make led_remove_lookup() NULL-aware It is a usual pattern in the kernel to make releasing functions be NULL-aware so they become a no-op. This helps reducing unneeded checks in the code where the given resource is optional.
