[PATCH 6.1 098/482] ALSA: hda: Disable jack polling at shutdown

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <redacted>

[ 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.
