From f5736c5871dd2ecb1cb08fe20c0c82b514dfdf87 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 23 Jun 2025 15:14:30 +0200 Subject: [PATCH] ALSA: hda: Disable jack polling at shutdown [ Upstream commit 1adcbdf54f76e1004bdf71df4eb1888c26e7ad06 ] Although the jack polling is canceled at shutdown in snd_hda_codec_shutdown(), it might be still re-triggered when the work is being processed at cancel_delayed_work_sync() call. This may result in the unexpected hardware access that should have been already disabled. For assuring to stop the jack polling, clear codec->jackpoll_interval at shutdown.
