From d6e321dcd7d42c492b305db50376bfa070b9b0cd Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Tue, 20 Feb 2024 00:11:20 +0100 Subject: [PATCH] backlight: lm3630a: Don't set bl->props.brightness in get_brightness [ Upstream commit 4bf7ddd2d2f0f8826f25f74c7eba4e2c323a1446 ] There's no need to set bl->props.brightness, the get_brightness function is just supposed to return the current brightness and not touch the struct. With that done we can also remove the 'goto out' and just return the value.
