From ba3f92938f2c01623546d4570ecc19a8b7786fa7 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 4 Apr 2021 09:52:52 +0200 Subject: [PATCH] HID: elan: Remove elan_mute_led_get_brigtness() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The led_classdev already contains a cached value of the last set brightness, the brightness_get callback is only meant for LED drivers which can read back the actual / current brightness from the hardware. Since elan_mute_led_get_brigtness() just returns the last set value it does not add any functionality, so we can just remove it.
