why snd_soc_suspend is not called

Hi, Mark

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);
platform_set_drvdata(device, &snd_soc_card);
platform_device_add(dev);

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.
