Subject: [PATCH 5.15 102/913] ALSA: hda/realtek: Fix audio regression on Mi Notebook Pro 2020

From: Kai-Heng Feng <kai.heng.feng@...onical.com>

commit f30741cded62f87bb4b1cc58bc627f076abcaba8 upstream.

Commit 5aec98913095 ("ALSA: hda/realtek - ALC236 headset MIC recording
issue") is to solve recording issue met on AL236, by matching codec
variant ALC269_TYPE_ALC257 and ALC269_TYPE_ALC256.

This match can be too broad and Mi Notebook Pro 2020 is broken by the
patch.

Instead, use codec ID to be narrow down the scope, in order to make
ALC256 unaffected.
