Eric Miao 5ff1ddf22b ASoC: skip resume of soc-audio devices without codecs
There are cases where there is no working codec on the soc-audio devices,
and snd_soc_suspend() will skip such device when suspending. Yet its
counterpart snd_soc_resume() does not check this, causing complaints
about spinlock lockup:
