I'm still seeing the problem:

ALSA device list:
  No soundcards found.

Here's the code that sets the CPU DAI name (in fsl_ssi.c):

        /* The DAI name is the last part of the full name of the node. */
	p = strrchr(np->full_name, '/') + 1;
	ssi_private = kzalloc(sizeof(struct fsl_ssi_private) + strlen(p),
			      GFP_KERNEL);
	if (!ssi_private) {
		dev_err(&of_dev->dev, "could not allocate DAI object\n");
		return -ENOMEM;
	}

	strcpy(ssi_private->name, p);

	/* Initialize this copy of the CPU DAI driver structure */
	memcpy(&ssi_private->cpu_dai_drv, &fsl_ssi_dai_template,
	       sizeof(fsl_ssi_dai_template));
	ssi_private->cpu_dai_drv.name = ssi_private->name;
	printk(KERN_INFO "%s:%u cpu_dai_drv.name=%s\n", __func__, __LINE__,
ssi_private->cpu_dai_drv.name);

...

	ret = snd_soc_register_dai(&of_dev->dev, &ssi_private->cpu_dai_drv);

You can see above that cpu_dai_drv.name is set to "ssi at 16000", but when
soc_bind_dai_link() looks for it, cpu_dai->name is set to "e0016000.ssi".  I
don't know where that string comes from, but it's not coming from my code.
