[ 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.
