[PATCH AUTOSEL 6.17] ALSA: hda/realtek: Add quirk for ASUS ROG Zephyrus Duo

[Sasha Levin <sashal@kernel.org>]

From: Adam Holliday <dochollidayxx@gmail.com>

[ Upstream commit 328b80b29a6a165c47fcc04d2bef3e09ed1d28f9 ]

The ASUS ROG Zephyrus Duo 15 SE (GX551QS) with ALC 289 codec requires specific
pin configuration for proper volume control. Without this quirk, volume
adjustments produce a muffled sound effect as only certain channels attenuate,
leaving bass frequency at full volume.

Testing with hdajackretask confirms these pin tweaks fix the issue:
- Pin 0x17: Internal Speaker (LFE)
- Pin 0x1e: Internal Speaker

LLM Generated explanations, may be completely bogus:

YES – The change cleanly fixes a user-visible volume-control bug on the
ASUS ROG Zephyrus Duo 15 SE without touching other systems and should be
backported.

- `sound/hda/codecs/realtek/alc269.c:3740` appends a new enum ID
  `ALC289_FIXUP_ASUS_ZEPHYRUS_DUAL_SPK` at the end of the fixup list, so
  no previously assigned indices shift, keeping existing quirks stable.
- `sound/hda/codecs/realtek/alc269.c:6170-6177` defines the quirk body
  with `HDA_FIXUP_PINS`, remapping pins 0x17/0x1e to the internal
  speaker and LFE path; these values match Realtek conventions
  (`0x9017015x`) and correct the bass channel attenuation defect
  reported in the commit message.
- `sound/hda/codecs/realtek/alc269.c:6733` wires the PCI SSID
  `0x1043:0x1652` for the GX551QS to the new fixup, tightly scoping the
  change to the affected laptop; other ASUS entries keep their existing
  fixups.
- No functional dependencies or architectural changes accompany the
  quirk—other ALC289 platforms retain their existing chains, and the new
  entry is not chained to anything else, keeping regression risk
  minimal.
- The bug is significant (volume slider leaves bass at full power) and
  has been validated with hdajackretask, so stable users of this
  hardware gain a real fix with negligible downside.

Given the targeted scope, tiny code delta, and user-facing impact, the
patch satisfies stable backport criteria. Suggested next step: queue for
the relevant supported stable series.
