Hi Liao
Thank you for your feedback
To me, the easiest way to see the issue is force return - EPROBE_DEFER on codec driver's probe function and call list_del(&component->card_list); before calling soc_cleanup_component(component); So list_del() will be called twice and you
will see the issue.
OK, I could reproduce your issue. And I think it will be solved if you can use list_del_init() instead of list_del() at soc_cleanup_component() ? (= without your patch)
- list_del()
- list_del_init()
If possible, I want to cleanup all component related resource at soc_cleanup_component(). Because it is easy to read / understand.
Thanks Morimoto san, I verified the solution works and agree with you. Will you send a patch to upstream?
Good to know !! I'm happy if you can update it :)
Thank you for your help !! Best regards --- Kuninori Morimoto
