Subject: [PATCH] ALSA: hda/realtek: Fix pop noise on ALC225
Git-commit: 3b36b13d5e69d6f51ff1c55d1b404a74646c9757
Patch-mainline: v5.6-rc7
References: git-fixes
Commit 317d9313925c ("ALSA: hda/realtek - Set default power save node to
0") makes the ALC225 have pop noise on S3 resume and cold boot.
So partially revert this commit for ALC225 to fix the regression.
