[PATCH] ALSA: hda/realtek: Add headset jack quirk for Thinkpad X390

[PATCH] ALSA: hda/realtek: Add headset jack quirk for Thinkpad X390

[Uzair Mughal]

The Lenovo ThinkPad X390 (ALC257 codec, subsystem ID 0x17aa2288)
does not report headset button press events. Headphone insertion is
detected (SW_HEADPHONE_INSERT), but pressing the inline microphone
button on a headset produces no input events.

Add a SND_PCI_QUIRK entry that maps this subsystem ID to
ALC285_FIXUP_THINKPAD_NO_BASS_SPK_HEADSET_JACK, which enables
headset jack button detection through alc_fixup_headset_jack()
and ThinkPad ACPI integration. This is the same fixup used by
similar ThinkPad models (P1 Gen 3, X1 Extreme Gen 3).

It looks like that the patch is malformed, failing one context line,
and neither git-am nor patch can't apply it cleanly.
Since the code change is trivial, I fixed it locally now.  But at the
next time, please make sure that the patch is really applicable.


thanks,
