However, snd_soc_find_dai() has lockdep_assert_held(&client_mutex) indicating callers must hold this lock, as the function iterates over the global component list. All other callers of snd_soc_find_dai() either hold client_mutex via the snd_soc_bind_card() path or use the snd_soc_find_dai_with_mutex() wrapper. Use snd_soc_find_dai_with_mutex() instead to fix the missing lock protection.
