Have you looked to see where the error is coming from?

• ret = snd_soc_dai_set_sysclk(codec_dai, SGTL5000_LRCLK,

• 				params_rate(params), 0);
  

• if (ret) {

• pr_err("%s: failed setting codec sysclk\n", __func__);
  

• return ret;
  

• }

Fix this in the CODEC driver, copying this code into the machine drivers is clearly not useful.

+static int __init imx_sgtl5000_init(void) +{

• int ret;
• imx_sgtl5000_snd_device = platform_device_alloc("soc-audio", -1);
• if (!imx_sgtl5000_snd_device)

• return -ENOMEM;
  

We're not accepting new drivers using soc-audio, you should use a regular platform device and register the card with snd_soc_register_card().
