[PATCH v2] ALSA: hda/realtek: Chain in pop reduction fixup for ThinkStation P340

[Peter Ujfalusi]

Lenovo ThinkStation P340 uses ALC623 codec (SSID 17aa:1048) and it produces
bug plock/pop noise over line out (green jack on the back) which can be
fixed by applying ALC269_FIXUP_NO_SHUTUP tot he machine.

Convert the existing entry for the same SSID to chain to apply this fixup
as well.

Hi Takashi,

Changes since v1
- instead of deny_list use chained fixup to fix the plock/pop noise

Changes since RFC:
- Fixed up the PCI ID

ever since I have this workstation (three weeks) the plock/pop noise on playback
start bugged me. So far the only solution I have found is to disable the
power_save which I find acceptable on a desktop compared to the pops.

The alsa-info.sh output is can be found here:
http://alsa-project.org/db/?f=414b1b236fc73db386ad4f938bc3b304f6b30b05

Missing details from alsa-info output:
# lspci -nnk | grep -A2 Audio
00:1f.3 Audio device [0403]: Intel Corporation Comet Lake PCH cAVS [8086:06c8]
        DeviceName: Onboard - Sound
        Subsystem: Lenovo Device [17aa:1048]

CPU: i9-10900k

The machine have ALC623 codec and the jacks are correctly discovered and they
do what they supposed to be.
When I have the headset connected to the front and audio is routed there the
line out (green jack) from the back still prodices the plock/pop.

Is there a known quirk for similar issue or a better way to handle it?
