[PATCH v2] ALSA: hda: conexant: Fix headset auto detect fail in the polling mode

From: soxiebing
Date: Fri Jul 26 2024 - 06:08:31 EST


From: songxiebing <songxiebing@xxxxxxxxxx>

The previous fix (7aeb25908648) only handles the unsol_event reporting
during interrupts and does not include the polling mode used to set
jackroll_ms, so now we are replacing it with snd_hda_jack_detect_enable_callback.

V1 -> V2: fix char persent compile error

Fixes: 7aeb25908648 ("ALSA: hda/conexant: Fix headset auto detect fail in cx8070 and SN6140")
