[PATCH AUTOSEL 6.18-5.10] ALSA: hda/realtek: Add quirk for ASUS VivoBook X509DAP

[Sasha Levin]

From: Andrei Faleichyk <andrei.faleichyk@xxxxxxxxxxxx>

[ Upstream commit 3580bc53520ce4efc94ece5886ad3670b93667ba ]

The internal microphone on ASUS VivoBook X509DAP (subsystem ID
0x1043:0x197e) is not detected without a quirk entry. Add
ALC256_FIXUP_ASUS_MIC_NO_PRESENCE to fix the issue.

LLM Generated explanations, may be completely bogus:

The background search finished. A repo-wide `git log -S '0x197e'` turned
up nothing related to this HDA quirk (only unrelated hits in other
subsystems), and there are no prior commits from Andrei Faleichyk in
`sound/hda/` in this tree — consistent with this being a new, standalone
quirk addition.

**Verdict for Linux 6.18.44:** backport **YES**. One-line
`SND_PCI_QUIRK` for ASUS VivoBook X509DAP (`0x1043:0x197e`) using the
existing `ALC256_FIXUP_ASUS_MIC_NO_PRESENCE` fixup; applies cleanly and
matches the pattern of other ASUS VivoBook mic quirks already in stable.

**YES**
