NAK. This breaks the error path and has to be fixed. Firstly, please, use
a new label like "esndreg," secondly, you have to add

 	clk_disable(hdmi->hdmi_clk);
 erate:
 	clk_put(hdmi->hdmi_clk);
 egetclk:
+	snd_soc_unregister_codec(&pdev->dev);
+esndreg:
 	mutex_destroy(&hdmi->mutex);
 	kfree(hdmi);
