OK. At present you can't have it both ways, i.e., SND_HDA_CODEC_REALTEK
with no LEDS. That driver apparently wants LEDS.
According to this commit:
commit 7cdf8c49b1df0a385db06c4f9a5ba1b16510fdcc
Author: Takashi Iwai <ti...@suse.de>
Date: Thu Jun 18 13:08:31 2020 +0200
ALSA: hda: generic: Add a helper for mic-mute LED with LED classdev
the Realtek and other drivers need LED support:
"""
Also, introduce a new kconfig CONFIG_SND_HDA_GENERIC_LEDS, to indicate
the usage of mute / mic-mute LED helpers. It's selected by the codec
drivers (Realtek, Conexant and Sigmatel), while it selects the
necessary LED class dependencies.
