Subject[PATCH 5.19 365/365] Revert "ALSA: hda: Fix page fault in snd_hda_codec_shutdown()"
Date
From: Takashi Iwai <tiwai@suse.de>

commit 53f07e9b010b966017e32be1ca1bbcbcc4cee73d upstream.

This reverts commit 980b3a8790b402e959a6d773b38b771019682be1.

The commit didn't consider the fact that ASoC hdac-hda driver
initializes the HD-audio stuff without calling
snd_hda_codec_device_init(). Hence this caused a regression leading
to Oops.

Revert the commit to restore the behavior.

Fixes: 980b3a8790b4 ("ALSA: hda: Fix page fault in snd_hda_codec_shutdown()")
