Re: [PATCH 4.19 012/206] ALSA: hda/realtek - Introduce polarity for micmute LED GPIO

Hi!

Currently mute LED and micmute LED share the same GPIO polarity.

So split the polarity for mute and micmute, in case they have different polarities.

+++ b/sound/pci/hda/patch_realtek.c @@ -94,6 +94,7 @@ struct alc_spec { /* mute LED for HP laptops, see alc269_fixup_mic_mute_hook() */ int mute_led_polarity;

• int micmute_led_polarity; hda_nid_t mute_led_nid; hda_nid_t cap_mute_led_nid;

This variable will be always zero in 4.19.130... so the patch does not really do anything.

In mainline, commit 3e0650ab26e20 makes use of this variable.

Best regards, Pavel
