[PATCH] ALSA: hda/realtek: Fix speaker mute LED on Lenovo ThinkBook 14 G8+ IPH

[Padhia Luo]

On the ThinkBook 14 G8+ IPH (SSID 17aa:393e, ALC287) the F1 speaker mute
LED never lights up, while the F4 mic mute LED works.

Both LEDs are platform LEDs registered by lenovo-wmi-hotkey-utilities and
default to the audio-mute / audio-micmute triggers, so the speaker LED only
follows a control carrying SNDRV_CTL_ELEM_ACCESS_SPK_LED. No control on
this machine has that flag set, so snd_ctl_led never attaches anything and
/sys/class/sound/ctl-led/speaker/card0/list stays empty. The mic LED is
unaffected because MIC_LED is set from the SOF topology on the DMIC
control, which does not go through the codec fixups at all.

The pin configuration of this machine matches the ThinkPad pin quirk that
selects ALC285_FIXUP_THINKPAD_HEADSET_JACK - pin_config_match() masks out
the sequence/association nibbles, so 0x14=0x90170120 still matches the
0x90170110 in the table. That fixup chains into ALC269_FIXUP_THINKPAD_ACPI,
but hda_fixup_thinkpad_acpi() returns early because is_thinkpad() is false:
a ThinkBook exposes neither LEN0068/LEN0268 nor IBM0068. Therefore
snd_hda_gen_add_mute_led_cdev() is never called and spec->vmaster_mute_led
stays 0.

The vendor fallback SND_PCI_QUIRK_VENDOR(0x17aa, "Lenovo XPAD",
ALC269_FIXUP_LENOVO_XPAD_ACPI) would have handled this correctly - the
machine does expose LHK2019 and VPC2004, so is_ideapad() is true - but it
never runs: the pin quirk has already set codec->fixup_id, and
snd_hda_pick_fixup() returns immediately in that case.

Add an SSID quirk selecting a fixup that keeps everything the machine
currently gets (headset jack handling plus the X1 Gen7 DAC routing) and
additionally runs the ideapad ACPI setup. It chains into
ALC287_FIXUP_LENOVO_YOGA_PRO7, which already combines
alc285_fixup_thinkpad_x1_gen7 with ALC269_FIXUP_LENOVO_XPAD_ACPI, so the
resulting chain differs from the current one only by the added ideapad step
and cannot regress the analog output or the headset jack.

Tested on 7.1.5 on the affected machine: the speaker LED group is now
populated at probe time without any userspace help, and the F1 LED
follows the mute state.  Compared against a boot with the previous fixup
selection, the mixer control list (names and numids) and the registered
jack input devices are identical.

Note that the underlying mismatch is not specific to this SSID. Any Lenovo
non-ThinkPad whose pins collide with a ThinkPad pin quirk loses its mute
LED the same way. Letting hda_fixup_thinkpad_acpi() fall back to the
ideapad check would cover the whole class at once, but that touches a
helper shared with every ThinkPad, so this patch only fixes the machine
that was actually tested.
