commit a0a4bf57a977 ("ASoC: core: delete component->card_list in soc_remove_component only") was trying to fix a kernel oops when list_del was called twice without re-init the list. Use list_del_init() can solve it, too. Besides, it will be more readable if we cleanup all component related resource at soc_cleanup_component().
