ALSA: hda/realtek: Add mic-mute LED quirk for the HP 245 14 inch G10
The HP 245 14 inch G10 Notebook PC (codec SSID 103c:8ba4, ALC236) is not
listed in alc269_fixup_tbl[], so the codec falls back to the vendor-wide
HP entry (ALC269_FIXUP_HP_MUTE_LED). That entry only registers a speaker
mute LED (hda::mute); no microphone mute LED class device (hda::micmute)
is created, so muting the microphone never lights the LED on the F8 key.
On this model the microphone mute LED is wired to COEF 0x35 bits 2-3 (the
same register as ALC236_FIXUP_HP_MUTE_LED), but with the opposite sense:
1 << 2 lights the LED and 2 << 2 turns it off. Setting
micmute_led_polarity = 1 makes alc_update_coef_led() write the level that
matches the hardware.
The speaker mute LED (F5) keeps being driven through the HP_Mute_LED DMI
string, exactly as the current fallback does.
Add ALC236_FIXUP_HP_MUTE_LED_MICMUTE_COEF_INV for 103c:8ba4.
