From 086aeca907789bd2604f16f07bfc073b19015015 Mon Sep 17 00:00:00 2001 From: Armin Wolf Date: Fri, 30 Oct 2026 20:46:44 +0100 Subject: [PATCH] platform/x86: uniwill-laptop: Implement .hw_offloaded trigger callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit 8e04e5382aa9 ("leds: trigger: Add hw_offloaded() callback and provide trigger_may_offload_to_hw attribute") the LED subsystem allows triggers to report if they are being offloaded to the underlying hardware. Implement the necessary callback so that the LED subsystem knows that the lightbar trigger is always offloaded to hardware.
