Hi, I tested the patches with the following setup. Please note I tested the microphone mute led by GUI, as the hotkey does not work on this system. 1. Downloaded the below patches from patchwork 9518737 Awaiting Upstream [v2,1/6] dell-led: remove GUID check from dell_micmute_led_set() 9518761 Awaiting Upstream [v2,2/6] ALSA: hda - use dell_micmute_led_set() instead of dell_app_wmi_led_set() 9518741 Awaiting Upstream [v2,3/6] ALSA: hda - rename dell_led_set_func to dell_micmute_led_set_func 9518725 Awaiting Upstream [v2,4/6] platform/x86: dell-laptop: import dell_micmute_led_set() from drivers/leds/dell-led.c 9518727 Awaiting Upstream [v2,5/6] dell-led: remove code related to mic mute LED 9518735 Awaiting Upstream [v2,6/6] dell-led: move driver to drivers/platform/x86/dell-wmi-led.c 9520053 Awaiting Upstream [v2,6+/6] platform/x86: dell-wmi-led: fix coding style issues 2.
