If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From tiwai@xxxxxxx Mon Oct 24 16:49:03 2022 From: Takashi Iwai <tiwai@xxxxxxx> Date: Mon, 24 Oct 2022 16:39:31 +0200 Subject: Revert "ALSA: hda: Fix page fault in snd_hda_codec_shutdown()" To: stable@xxxxxxxxxxxxxxx Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>, Sasha Levin <sashal@xxxxxxxxxx>, linux-kernel@xxxxxxxxxxxxxxx Message-ID: <20221024143931.15722-1-tiwai@xxxxxxx> From: Takashi Iwai <tiwai@xxxxxxx> This reverts commit 7494e2e6c55ed192f2b91c821fd6832744ba8741. Which was upstream commit f2bd1c5ae2cb0cf9525c9bffc0038c12dd7e1338. The patch caused a regression leading to the missing HD-audio device with ASoC SOF driver. It was a part of large series and backporting it alone breaks things while backporting the whole is too intrusive as stable changes. And, the issue the patch tries to address is a corner case, hence it's better to revert.
