[alsa-devel] why snd_soc_suspend is not called

Excuse me, I am confused about snd_soc_suspend.
When realizing cpu_dai->driver->suspend, we found snd_soc_suspend is not called.
In fact, even soc_probe is not called since no soc-audio device.
We manually alloc soc-audio deivce before in platfrom.c.
dev = platform_device_alloc("soc-audio", -1);
When running, system recommend using snd_soc_register_card instead.
After doing such modification, the audio could work.
But strangely snd_soc_suspend is not called, as well as soc-probe.
So cpu_dai->driver->suspend will no be called accordingly.
If manually add "soc-audio" in arch/, the soc-probe can be called.
But snd_soc_suspend still fail to be called.
Could you give me some suggestion?
Thanks a lot.
