[PATCH v3 16/17] ASoC: Intel: bdw_rt286: Refactor jack handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use link->exit() rather than pdev->remove() to unassign jack during card
unbind procedure so codec link initialization and exit procedures are
synergistic.

Also, there is no need to perform search for codec dai in suspend_pre()
and resume_post() ourselves. Use snd_soc_card_get_codec_dai() instead.
