Use the new sound control LED layer instead the direct ledtrig_audio_set() call - see 22d8de62f11b ("ALSA: control - add generic LED trigger module as the new control layer").
Don't we need to select SND_CTL_LED from SOF to make sure that the LED trigger module is available?
This feature is optional and the current code does not even forcefully select the LEDS_TRIGGERS and LEDS_TRIGGER_AUDIO, too. There was IS_REACHABLE(CONFIG_LEDS_TRIGGER_AUDIO) condition. I think that this change should be handled separately (if required).
Unfortunately, I forgot to call snd_ctl_led_request() to load the LED trigger module when available. I will send v2 ASAP.
