tiny6410、linux2.6.38内核里编译进去uda134x驱动后，发现probe函数没有执行。
ps：

开发板自带的wm9713驱动就会运行

我在static int __init wm9713_init(void)，
static __devinit int wm9713_probe(struct platform_device *pdev)，
static int wm9713_soc_probe(struct snd_soc_codec *codec)都加了打印信息，都打印出来了。

检查一下有没有注册相应的platform device

我是新手，请问platform device都是在哪里注册？谢谢！

我加载的是i2s声卡uda1341驱动，找了一下，加载的时候确实没有注册这个i2s总线，而导致match出错，是不是可以通过先加载i2s驱动再加载uda1341驱动来解决呢？

印象中是在arch/arm/mach-s3c64xx/mach-mini6410.c中

这个问题解决了嘛。楼主，我也遇到了
