[PATCH] Revert "ALSA: hda: Fix page fault in snd_hda_codec_shutdown()"

[Takashi Iwai <tiwai@xxxxxxx>]

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()")
Link: https://lore.kernel.org/r/3c40df55-3aee-1e08-493b-7b30cd84dc00@xxxxxxxxxxxxxxx
